How to connect two TVs to one digital TV antenna with amplifier.
So let’s start with the cable.
It is necessary to clean only the upper part without damaging the screen and foil
collect the foil and shield wire into a twist
now we clean the central core of the required length.
Next, put on the connector indicated by the arrow with twisting movements on the cable.
At the same time, it is necessary to ensure that the central core does not touch the screen and foil, this is very important!
Next, we need a divisor and not a SIMple one, but with a matching.
The figure shows that one strip can pass power.
If our antenna has an amplifier, then it needs to be powered with something and this must be done so that the power goes to the amplifier, and not to the TV jack.
The divider with matching is divided by bandwidth, but this is a completely different song that you don’t need to know, just remember that the divider from a satellite dish is suitable for digital TV, but on the contrary it will definitely not work.
The divider is called the divider, that is, it will divide the signal, which means we need a good received signal.
If the signal is unstable, then you should not expect good quality.
It’s just that the voltage will not go to the amplifier through it, but the output, as always, was found.
We will apply the usual divider plus the power supply, but we will turn it on before the divider, thereby supplying power to the amplifier.
We will need additional material in the form
These are two gizmos connectors dad mom.
So you can solve the problem with a conventional divider without going through the power supply, the antenna will work.
So we figured out the first method, let’s proceed to the next.
Two TVs to one antenna. how to connect
Hello blog readers !
Today, no one is surprised by the presence of two, three or more televisions in a family.
Wealth is growing, which means all kinds of wishes appear, and for someone it may just be necessary to have two, maybe three or more TVs in the house.
But it’s not a hunt for each separate TV to lead a separate antenna, and sometimes it is SIMply impossible to do this.
The question naturally arises, how to connect two TVs to one antenna and this is possible.
There are several options for solving this problem, it is possible to connect two TVs to one antenna using splitters, dividers, amplifiers.
Of course, with some methods there are signal losses, but we will try so that we have two TVs connected to one antenna without signal loss.
And we will try to use as few additional devices as possible.
Now about everything in order.
How to connect two TVs to one antenna without signal loss and without a splitter.
Many people face such a problem that when using all kinds of splitters, tee dividers and other devices for splitting a signal.
The signal is accordingly lost, it is divided by 2 and in three shorter does not show anything.
Now I will tell and try to show in the pictures a certain method that I used with my friend.
Once we got together in a bathhouse, and he brought there an old TV from his parents, though it already had a dvb t2 tuner.
Since the antenna in the bath was already standing and there was a large TV, he thought that he would not have problems with the connection, only he needed to get the divider.
We were not in the bath for long that day.
And the next day when he brought the tee and the divider called me to try to connect all this, because he did not work.
We suffered for a very long time, tried all possible options, even tried the option with amplification, because he had an antenna with an amplifier that did not work.
Changed the amplifier, changed the power supply board, in general, spent a lot of money.
And the solution to this problem lay so close to the surface that I was just shocked when it was discovered.
Briefly what we did.
Since he already had one TV and showed it before it was clear that there was a signal.
True, he was not strong enough, only about 48% strength, but the quality was 100%.
And this despite the fact that the antenna was sharpened from the factory for an amplifier like this
But the amplifier burned out long ago and therefore it was used without an amplifier, that is, no power was supplied.
What we did was just take two cables and plug them into the antenna amplifier.
Unfortunately, there was no photograph of this process, but I piled something the same mount there.
Yes, they just took two males, stripped the insulation, fastened the shielding braid together, the foil was also connected together.
Then I just put this huge twist into a regular place in the amplifier.
It was certainly not easy, but at that time it was all the same the main thing to try.
Blue arrow central veins. fit perfectly and fasten with a screw.
Red shows how we fix the screens. of course, you will have to tinker, but everything is within the normal range.
Yellow shows the moment so that the screens do not, under any conditions, touch the central veins.
Then we fixed it all with regular screws and enjoyed the TV both on the veranda and in the dressing room.
What was our surprise with him at that time is difficult to describe, but two TVs from one antenna worked to the fullest.
After the operation done, I did the same at home to connect 3 TVs and threw out all the amplifiers from the circuit.
The signal was stable on both TVs, also from 45 to 50% strength, the quality was from 90 to 100%.
No hang-ups or breaks in transmissions.
Take this easy way for yourself and use.
Do not overpay for all possible splitters, dividers, amplifiers, and so on, if it is not necessary.
Just first check the quality and signal strength with the connection of 1 TV from one antenna, and then make the appropriate conclusions.
That’s all, apply the obtained method to health.!
Connecting TVs to a satellite dish
Such television uses a system of orbiting satellites, including the latest third generation meridians and others, which are in space. Television stations send a signal to them, and they return it to large areas of the earth, where each satellite dish receives it and reflects it on the collecting head, receiver and TV. Thus, images and sound appear on the screens. And you can tune the Tricolor TV and NTV Plus channels on one satellite dish.
Previously, to connect a satellite dish, they bought 1 set of equipment designed for one TV. Time passes, the owners acquire a second TV, wanting to connect to the existing cable. There is a problem how to connect two TVs to a satellite dish by yourself. Read about how to watch Tricolor TV on two TVs in the article.
There are only 2 ways to connect TVs to one satellite dish, the first is the use of an RF modulator, the second is the use of 2 or 3 receivers, that is, a separate one for each TV.
An easy way to connect two TVs to an antenna
How do I connect multiple TVs to one antenna? To do this, branching is made in the existing cable using a conventional tee, into which all central cores are inserted. Then they connect the first TV and connect it additionally. But this method leads to a violation of the coordination in the antenna cable itself and the mutual influence of TVs on each other. This method reduces the signal level, there is a lot of interference on the screens, so no one uses it.
To connect additional TVs, if only one antenna is available, splitters (crabs) are used. A splitter is a cable splitter with three or more resistances in the case, as well as leads for TVs.
What are the splitters
Splitters match waveform impedances, maintain the signal without letting it fade, eliminating noise and interference, improving the image.
Antenna crabs split the cable between two TVs, or more, they come in:
Such splitters have one input and several outputs, usually for a home they choose 2 or 3 TVs. They evenly share the signal from a common antenna. For example, the input is 12 dB, which means that an antenna splitter installed on 2 TVs will output 6 dB signals from each of the outputs. If we install a splitter for 3 outputs, it will be 4 dB, respectively. Passive splitter circuits use transistors, or transformers.
When buying a crab, you need to pay attention to its characteristics, namely:
- number of outputs;
- attenuation level;
- the presence of an RF amplifier.
It is also worth paying attention to the frequency range that it can pass. If this is a high satellite bandwidth of 5-2400 mNz, then it is also suitable for terrestrial TV. But 5-1000 mNz can be used exclusively for terrestrial TV, this must be taken into account.
The splitter has 2 to 8 outputs. Buying it for only 2 TVs, think about the possible connection of additional receivers in the future. Pay attention to the attenuation level, the lower it is, the better.
A splitter, which has a built-in RF amplifier, is called active; such a splitter is capable of maintaining and increasing the signal, but it needs to be powered up. It can be a separate unit or by cable.
RF Modulator Applications
We use the existing tuner, connect the first TV with a tulip, connecting it to the HF modulator, then the second monitor. One receiver can connect 2 or 3 TVs, this number depends on the outputs on the rear panel. This method is SIMple, and the financial costs are small.
It is possible to switch channels, but only on the tuner, which may be in another room. Another disadvantage of this method is that both TVs show the same channel. The picture quality of a TV connected directly to the receiver will be better than others. As you can see, this method has many disadvantages. Therefore, it is advisable to use additional receivers, but this is expensive.
How to connect two TVs to one antenna
There are many different TV programs so that each family member can watch the one he likes, the question arises of installing a second or more TVs. How to solve this on your own and connect additional TV sets to an existing or self-made antenna.
The good thing about antenna cables is that even a non-professional can handle their routing and branching. To do this, you will need to plan the connection diagram in advance, clarify the number and type of splitters, plugs, adapters, connectors, perform installation.
At a high signal level, a passive crab is used to connect two TVs. For this, a high-quality cable (RK-75) with a small attenuation is needed, the less decibel is indicated on it, the better, and the characteristic impedance should be 75 Ohm with a frequency of up to 1000 MHz.
The connection diagram is SIMple. We connect the input of the splitter and the cable from the antenna together, and connect its outputs to TVs. If the image is bad, you need to check all the connections and the integrity of the cable itself.
So that everyone can easily cope with the connection process, we will consider it in more detail:
- prepare a splitter with built-in sockets for coaxial cables, F-connectors and a cable;
- choose the place to install the crab, and this is the shortest distance to 2 or 3 TVs;
- cut the cable from the antenna so that it can freely reach the crab;
- install the F-connector.
Disconnect the TVs from the mains. We prepare pieces of cable for each. We begin to install the connectors. This is done in this way:
- remove 1.5-2 cm of the upper cable insulation;
- pulling back the silver screen;
- we clean the center wire;
- wind the F-connector.
If the center wire protrudes more than 3 mm, it must be cut. Now we connect the cable from the antenna to the crab. In the same way, we connect each output of the splitter and the TV set.
Connection with an active splitter
Connecting two TVs to the existing one antenna is preferable to an active splitter, so they are replaced by passive crabs. In order for an antenna with an amplifier to improve the signal quality for 2 or 3 TVs at the output, a power supply unit with a filter is connected to one of the receivers, preferably with a regulator. Second exit, to next TV.
For SIMultaneous reception of analog and digital TV, you need to connect to the DVA-T2 set-top box. To do this, connect the free output of the crab to it, and then connect one of the TVs with a digital HDMI cable or bells.
Using additional receivers
This method provides for the installation of additional 2 or 3 or more satellite tuners, one at a time in the room where the TV is installed. Now each TV set will provide independent selection and viewing of the desired channel. Also read about connecting satellite TV to two TVs and all about connecting Tricolor TV to multiple TVs.
But this connection system requires the installation of electronic convectors, in which the number of outputs corresponds to the number of tuners. The most common heads have 2, 4 and 8 outputs, if you need even more, use a multiswitch, usually it is used for apartment buildings.
The most crucial moment here is the choice of the receiver. Some may not support certain parameters, so not all channels will be available to the user. It is difficult for an ordinary person to understand a huge number of complex devices, so you need to trust a specialist. The correct decision and the choice of the appropriate method will make it possible to provide the maximum number of TV channels with high-quality images.
How to connect two TVs to one antenna
A family dinner while watching the evening news is a picture you can see in almost every kitchen window in an apartment building. It’s no longer a luxury to have a TV in the kitchen. Watching your favorite TV series and talk shows can brighten up the routine kitchen chores of every housewife. Progress confidently stepped over the threshold of every house and apartment, and now instead of a black and white dimensional TV, in many houses on the wall in every room you can see a flat TV panel.
Before each owner of the second or even the third TV, the question naturally arose, how to connect two TVs to one antenna? If this circumstance baffles you, then read this article. It contains the solution to this SIMple problem.
How to connect two TVs to one antenna cable
It all starts with choosing the place where you want to split the signal in two. This is where you should cut the cable that you had from the antenna to your existing TV and where it is convenient to install the divider. This is especially true for an active splitter (remember that it needs to be powered by something).
Let’s say that you have already bought an additional cable and all the necessary tools are already at your fingertips (divider, mounting brackets, knife, tape measure and two antenna connectors for the first and second TVs). You should install the antenna plug that you had on the end of the antenna cable that will go into the divider. This is done with a knife to remove excess cable insulation. Make sure that the outer cable braid does not touch the center conductor anywhere. After the divider is connected to the antenna cable, you can start transmitting the signal.
Using a tape measure, measure the distance from the divider to each TV and cut two pieces of cable to the appropriate length. Install the antenna connectors on the ends of the cable. Connect the cable to the outputs of the divider. You should now have a parallel connection. You will use the principle of parallel signal distribution if one day you want to connect several TVs at once in your house.
Fasten the cable neatly with the help of compact fasteners along the plinth or lay it in the cable duct so that no one at home will trip over it and damage the wiring. Check out what you got. The ideal result is an equal, stable broadcast quality on the screens of both TVs.
Cable length and number of cable connections
Perhaps not everyone knows, but the length of the cabling can affect the quality of the “picture” on your TV. If the signal path from the antenna to the TV receiver is no more than 20. 30 m, then you probably won’t notice anything. But each subsequent meter of cable causes a drop in signal strength. This parameter is measured in this way. attenuation per meter of length. So plan your cable wisely, even if you don’t skimp on cable.
And those who were “greedy” and assembled the cable from fragments, and even more so saved on special sealed adapters, should understand that this will not affect the final result in the best way. Like water flowing through a leaky pipe, the TV signal will be lost, fade out with every twist, and noise may appear on the screen. Avoid unnecessary turns of cable in the house and take care of its integrity.
First, it is the strength of the TV signal that comes from the antenna. Its level can be checked using a signal meter or estimated thanks to the level indication in the menu on the TV screen (Fig. 1).
But here it would be nice to know at what frequency this digital television package (multiplex) can be received in your region. When you tune the TV manually, you must find the correct frequency (channel) and position the antenna to receive the best possible signal. Make sure that the achieved signal level is high enough to get acceptable broadcast quality after splitting it into two TV receivers.
In order not to install its own antenna for each TV, TV signal dividers come to the rescue (Fig. 2). They have other names, depending on their characteristics, which can also be heard often: splitters, splitters, CRABs and tapas (couplers). What are we dealing with? The clue in the name itself is an element of telecommunications, through which you can distribute the signal received by one antenna to several TV sets or, SIMply, split.
Outwardly, the divider has a shape that most of all resembles a metal box, the size of a matchbox. Its two opposite sides have connectors for cable entry and exit. As a rule, there is one input, and there can be several output connectors. And their number is a determining parameter when buying and installing a divider.
Some useful information
When you install an antenna installation from scratch, you are faced with a SIMpler task, because you can probably predict how many TV receivers will need a signal. If the antenna has already been installed, then the situation is somewhat different, because not only the technical side of connecting several TVs to one antenna is important, but also maintaining the quality of the previous reception. Several factors are at play here. Consider them.
It is good because it does not require a power source. But, splitting into two streams in a passive splitter, the TV signal in a certain way weakens by almost half, and if the splitter has three outputs, then three times, etc. This circumstance is almost imperceptible in large cities with high broadcasting power, but if your antenna is at a decent distance from the repeater or you use a long cable, then you should install an active type splitter.
This electronic device works without signal loss and even amplifies it thanks to the built-in transistor amplifier, which has a positive effect on its function:
- active divider output connectors provide undistorted voltage;
- it has a low level of intrinsic noise;
- there is no cross-signal distortion;
- the device has a wide dynamic range.
CRAB active type must be powered from a stabilized power source.The current consumption of the splitter. about 60 mA. can be provided from a nearby power outlet or via a high-frequency cable.
Connecting three or more TVs
As already mentioned, the circuit for connecting TVs to the divider is parallel. It should be noted that each next TV included in this scheme, to a certain extent, lowers the reception quality. If the installation of a separate antenna is still not included in your plans, but you want to connect three TVs (Fig. 6), then the same divider into three outputs will help you out. True, it will be much more effective to install an active splitter with three or more outputs, according to the number of receivers.
Before purchasing a splitter, do not forget to specify for which frequency range your splitter is suitable. The connection aLGorithm is identical to the scheme with two TVs, but there are variations. For example, if you want to connect in parallel an analog-to-digital converter (DVB-T2), then connect two TVs according to the classical scheme, and insert another CRAB into the remaining third output of the divider. You can connect a third TV and a decoder to it or use the loop output on the set-top box (not all set-top boxes have a loop output).
Unacceptable connection option
There is a fairly SIMple method that allows you to connect two TVs to one satellite dish. However, he is unlikely to suit anyone. This method is to use one receiver. In this case, the first device is connected to the first TV through the tulip, while the second tulip output is connected to the HF modulator, which allows you to connect other monitors.
Unfortunately, this connection option has a lot of disadvantages. Here it is possible to control channel switching only in the room where the receiver is located. In this case, two TVs will show one channel. In addition, the picture quality decreases.
The best connection option
In order to properly connect two TVs to a satellite dish and provide the possibility of independent viewing, each device must be connected to a receiver. After the signal hits it, it can be divided as convenient for the user and, accordingly, independently control the channels. TV channels are switched on the receiver, so different monitors will broadcast different channels. Buying and connecting two receivers is not cheap pleasure, but there is no alternative to this.
A separate such device is installed in each room. The installation is done on a daisy-chain basis. In this case, all devices are connected to the loop-through output.
How to connect two TVs to a satellite dish
Modern technologies provide people with a lot of new opportunities. So, several decades ago, having a TV in the house that broadcast several channels was a great happiness. Today, having a television broadcasting hundreds of channels is not enough. A large number of users want to install two copies of such equipment at once, which are distinguished by a high-quality picture from satellite television.
When purchasing and installing a set of such televisions at home, only a small percentage of subscribers are aware that this set is intended only for one television set. Families often do not have the same tastes, so there are several such devices in the house. In this case, the owner faces a serious problem regarding connecting them to a satellite dish and dividing the signal.
There are two main ways that you can connect two TVs at the same time:
- using an RF modulator;
- with two receivers.
Choosing a receiver is a task for a professional
To effectively connect two TVs to one antenna, it is very important to choose your receiver wisely. This task can be called the most responsible, requiring a special approach. There are cases when the receiver does not support certain parameters, so you will have to abandon individual TV channels or purchase another receiver.
In recent years, the number of receivers produced has been continuously increasing, so it is SIMply pointless to recommend a specific model. Any receiver is a complex device with a number of characteristics. It is SIMply impossible for an ordinary user to understand them in full. Therefore, the choice of a model should be trusted only by specialists. Only this approach will allow you to provide yourself with a high-quality picture and the maximum number of television channels.
How do I split the signal to connect two TVs? This requires a device called a splitter, or splitter. It should have as many outputs as it is intended to connect TV sets. If there are more outputs or in the future it is planned to connect TVs, then the extra outputs will need to be plugged. 75 Ohm resistors.
The splitter will split the signal from the antenna into two devices. Therefore, you will need two pieces of wire coming from the separator, adapter plugs (for connecting the cable to the TV receiver) and connectors that will be attached to the ends of the cable. The antenna can be any, one of the common options is the Polish antenna.
There is the option of connecting two antennas to one TV. This is done in order to combine VHF and UHF waves into one receiver, or to increase the number of channels. Splitters or mixers can also be used for these purposes.
How to make an F-connector
- Remove the insulation from the end of the cable about 1.5 cm;
- Bend the shield (cable braid), it is important not to close the braid with the central core;
- Peel back the foil;
- Remove the inner insulation layer about 1 cm;
- Screw on the F-connector;
- Cut off the central core (leave 2-5 mm).
How to connect two antennas to one TV via a splitter
The use of multiple TVs in one apartment is not new for a long time. over, if everything is easier with interactive television. it is enough to agree with the provider about connecting several devices, then what to do with on-air television broadcasting? If another TV receiver appears in the apartment, the question arises as to how two TVs should be connected to one antenna. Is it possible to attach even more equipment, and how this will affect the reception. Consider how to split the signal from a wave receiver to two home TVs.
When connecting a second TV, you will need to follow these steps:
- Choose a splitter. If you know how to solder, then you can choose a device that requires soldering. It should be noted that such a connection will be more reliable than any others. If you do not plan to solder, then it is better to take a separator with built-in sockets for television cables.
- The place for installing the divider should be as close as possible to both TVs with convenient antenna cable connection. You can connect TVs to both passive and active antennas.
- The plug is cut off at the antenna cable: the antenna connection will now be made via the F-connector. And the length of the wire must be sufficient to connect to the splitter.
- Two pieces of wire are taken, which will be connected from the splitter to the TV sets. Use a 75 ohm coaxial cable for this.
- Connect the F-connectors to the ends of all cables. You can use another type of connector, but this one is considered the most convenient and SIMple. How to make such a connection is described in more detail below.
- Connect the antenna cable and the two cut cables with the divider. It is advisable to carefully lay the cables along the walls for the least damage.
- The remaining free ends are connected to TVs through adapter plugs. Do not forget to de-energize devices before connecting.
- Check the functionality of both receivers.
- If there is interference, you can try checking the connections or re-crimping the cable.
TV signal divider
A signal divider is a device that has one input and several outputs for splitting a signal between different devices. That is, an antenna cable is fed to the input, and cables are fed to the outputs, which are connected, for example, to TVs.
The splitter can be active or passive. A passive splitter will route the TV signal to two TVs, but each stream will lose half its strength. Such a splitter does not need additional power supply, but the more outputs there are, the weaker the final signal will be. If there is a good reception level from the antenna, then you can get an acceptable image quality. In such a situation, a conventional tee can also be used. It doesn’t matter which cable to insert into which connector. it’s all the same.
In another situation, active splitters come to the rescue. They have built-in transistor amplifiers, which ensure no attenuation, and sometimes amplification of the signal, undistorted voltage at the outputs, no cross-distortion.
Active dividers have different bandwidths for terrestrial and satellite TV. The second has more. Such splitters can be used for both digital and analog broadcasting, but terrestrial ones for satellite broadcasting cannot.
Another important nuance of active dividers is providing it with power. There are splitters with power pass. Then there will be no difficulties in connection. But not all of them are equipped with this function. Then another method of fastening will help. Power must be supplied between the antenna and the splitter. This requires an additional component, something like an adapter. It has a threaded needle on one side. This end must be screwed into the divider input. And the other end is the antenna socket, to which you need to connect the power supply separator.
This method is also suitable for connecting digital receivers. Then in the set-top box menu there is no need to connect the power of the wave receiver, it will be provided through the power supply unit. In this case, the power supply is recommended to take an adjustable one in order to lower the gain if necessary. It happens that active elements excessively amplify the signal, due to which the channels may show poorly or some of them are absent.
The separation of a digital signal does not differ from an analog one, so there are no special nuances of how to connect a second TV. The only thing is that digital broadcasting works only in the decimeter wavelength range, so the separator must be able to separate just such frequencies.
In order to solve the problem of how to properly connect two TVs to one antenna, you need to pay attention to some points:
- TV signal strength. It can be measured using special devices or indication of the reception level on the TV. Before branching the cable to two TVs from one antenna, you must ensure the best signal level.
- Cable length and number of connections. The greater its length, the weaker the signal will be at the output, so unnecessary turns should be avoided. The same applies to connections: the more there are, the greater the loss in quality.
You can also use a splitter when connecting two TVs to cable TV. Since cable TV has a high image quality, the received signal for two receivers should be quite acceptable, even with a passive splitter.
The scheme of a passive antenna splitter has the form of the formula: R1 = R2 = R3 = 25 Ohm.
How to connect to the TV splitter is shown in the following figure:
If you wish, you can solder the divider to the amplifier yourself, but without any problems it can be used only for analog broadcasting. For a digital and a satellite, it is better to purchase ready-made devices. Further, we will take a closer look at the connection process itself.
After the antenna splitter is connected, a significant deterioration in the quality of the resulting image on the TV is possible. Most likely, the original signal is not enough for a good picture transmission. In such a case, the reception status may be affected by the TV amplifier. It is better to install it instead of the usual splitter as close as possible to the outdoor antenna. Such a device requires additional power supply, therefore, a socket must be provided. A splitter with an amplifier, although it has a higher cost, but it solves the problem with the loss of a TV signal.
Another way to get a better signal is to install a more powerful antenna or equip it with an antenna amplifier. If you are just going to install a wave receiver, it is better to immediately take care of the signal quality and its margin in case of splitting into several television devices.
To reduce noise and interference, you can install ferrite rings at the ends of the cable near the devices themselves. Such thickenings can be seen on power supplies, for example, for laptops.
An increase in the signal from a wave device can be realized through the interaction of a preamplifier and a distribution amplifier. The first. the antenna amplifier. is located between the antenna and the splitter, and the second is already in front of it. In this case, it is desirable to match the gains. Over-amplification of the signal threatens the same negative consequences as its lack.
So, you can cope with connecting the antenna to several TV sets yourself. This does not require special knowledge in electronics, but only requires the implementation of safety measures when working with electrical appliances and accuracy when preparing the cable. The better the cable is crimped, the less loss of useful signal will be.
With good reception, a passive separator is sufficient. But if necessary, TV amplifiers are installed that can work in conjunction with antennas. However, in this case, it is imperative to ensure that the signal is not excessively increased, so that the image on the screens is not distorted. You can use regulated power supplies for this.
Connecting multiple TVs to one antenna
Modern digital television, other formats of broadcasting by radio signal. this is a huge amount of interesting content. To get it, it is enough to correctly tune the antenna and lay the TV cable. But here the modern user has a problem. In most houses and apartments, you need to connect 2 TVs to one antenna. With the help of SIMple technical solutions, today several consumers can be connected to one cable.
Dividers with and without matching
An electronic circuit of SIMple dividers completely separates the signal receiving and secondary transmission circuits. This creates some problems. In particular, it is not possible to transmit power over the cable to an active antenna.
Matching dividers do not have this disadvantage. Between their outputs and inputs there is a so-called power transmission circuit to an antenna with an amplifier. Some models transport power from any cable. Others offer this only when power is connected to a specific output.
Materials required for work
Modern technical solutions for laying a cable network do not require the user to solder or perform other work that requires special skills. To connect a second TV, you will need:
- the selected number of splitters of one type or another;
- the number of F-connectors required for switching;
- marking tool, marker, for easy labeling;
- sharp thin knife;
Dividers with agreement
The divider with matching is connected so that its output with the power transmission circuit is switched to a wire with a voltage conversion unit. In the circuit, the antenna cable is connected to the splitter input. Then the TVs are switched to two or more divider outputs. The user will need:
- cut the standard antenna wire with the power supply;
- crimp the two formed ends with F-connectors;
- prepare a wire of suitable length to connect a second TV.
Connecting to an active antenna
There are several ways to connect a second TV to an active antenna. The choice of option depends on the power scheme that the receiving device uses. Ideally, if a split system is built in an apartment or house. That is, the active antenna amplifier is located indoors and has its own individual power supply. In this case, you need to proceed in the same way as in the version with a passive receiver.
The operation of a linear divider is as SIMple as possible to understand. These devices have one input and several outputs. SIMple models allow you to connect two or three TVs to one antenna. Complex ones distribute the signal to a larger number of consumers. In retail, it’s easy to find the 8-outlet model.
It should be understood that linear dividers do not allow arithmetically dividing the incoming power without signal loss. The sum of the parameters at each of the outputs will be less due to drops during conversions and distortions in the electronic circuit of the splitter itself. Therefore, to obtain a signal of proper quality, active dividers or separate amplifiers for each TV are used.
Connecting to a passive antenna
The second TV is connected to a passive antenna using SIMple linear or non-linear dividers. First, you need to connect the cable from the receiving device to the input of the first splitter in the chain (or the only one in the network of two TVs). This is done by attaching one of its ends to the antenna leads, crimping the other and screwing the F-connector onto the divider.
Then two more wires are prepared for connecting the TV. A sufficient length is measured, a gasket is made around the rooms. The ends of the cables are crimped with connectors. The latter are connected to the splitter outputs and antenna inputs of TVs.
An active antenna for two TVs can also be connected with conventional splitters. This will require:
- make two cables the length required to connect a TV;
- crimp the ends of the cables;
- if necessary, prepare an adapter from the cable socket to the F-connector.
The connection diagram provides for connecting the antenna cable to the power supply in front of the splitter. That is, its output end is connected to the input of the divider. In this case, an adapter may be required for switching. TVs are connected to the splitter outputs with previously manufactured and crimped cables.
How to crimp F connectors
The process of attaching a connector to the end of a cable is called crimping. It’s pretty SIMple.
- The end of the cable is marked with a distance of approximately half the length of the F-connector.
- Using a sharp knife, the outer insulation of the wire is trimmed and removed. This must be done carefully, without damaging the shielding braid or foil.
- The braid-screen must be carefully divided into two parts, folded back and laid evenly on the cable insulation.
- The inner layer of dielectric, protecting the main core, should be removed.
- The thick main conductor is inserted into the hole in the inner part of the F-connector and pushed in until it stops.
- The outer part of the F-connector with a thread is screwed onto the braid laid on the cable, if necessary with pliers.
How to connect two TVs to one satellite dish
A dozen years ago satellite TV was an expensive pleasure, but today it is a daily routine and many do not want to be satisfied with only one TV with a wide variety of TV programs. The issue of connecting multiple TVs to one satellite dish becomes more and more urgent.
In this article I will try to convey all the ways to connect two or more TVs to one satellite dish.
Unacceptable connection options.
Alternatively, many inexperienced users or SIMply lovers of satellite TV in the old fashioned way divide the satellite signal through a SIMple splitter-divider for analog TV.
In many cases this works well or acceptable for a certain amount of time, but there is always a chance of burning something up. One or several parts may fail. a converter, a disc or even a receiver. You need it ?
If you, for example, watch only one satellite. amos (for example). There is an option of connecting a second satellite receiver to the LOOP output of the first.
In this connection option, it will be possible to independently view different TV programs of the same subband.
What does it mean ? The satellite converter has two local oscillators for receiving the upper lower sub-band of satellite frequencies.
If the first receiver is receiving from the upper sub-band, then they will show on the second. This is not one channel, but several, perhaps even all. depending on the satellite and broadcast frequencies.
Alternatively, it is also possible to view one satellite channel on several TVs if they are connected in parallel to one or to independent outputs (scart, tulips) of the satellite receiver).
Satellite television. The best option for connecting a satellite dish to multiple TVs
If we talk about two, three or four TVs connected to one satellite dish. Option of twin and quad converters. “satellite heads” with several outputs.
Perhaps the most optimal.
From each converter 2 or 4 cables come out, connected to separate disks, each of which to separate satellite receivers and TVs.
In this case, we get independent reception of different satellites and channels on all TVs.
Another very good option for independently connecting one or more satellite dishes to two or more TVs is to use a multiswitch for this purpose. But in many cases, one antenna is rarely enough.
I hope the information was useful and you will be happy to watch your favorite TV shows regardless of your wife, children or parents in another room or kitchen.
