Setting up digital channels

High definition digital television. it is a modern television broadcasting standard that provides the highest picture quality in all reception conditions. To tune digital TV channels on your TV, it must be equipped with an HD viewing function. In recent years, an increasing number of TV models equipped with this technology have been produced.

To configure the channels on such TV sets, it will be enough to carefully study the manufacturer’s instructions. For most devices, the sequence of actions is as follows:

  • Menu. Options. Automatic tuning. Start;
  • Select the Digital Channels section and click on start again;
  • In the Search Mode, select the item “Full”;
  • in the fields that appear on the screen, you will need to enter the following numbers: frequency (kHz). 314,000 (314 MHz) modulation. 256 QAM, speed. 6875 kS / s.

All modern TVs are equipped with a network search option. For those viewers who do not want to waste time manually tuning channels, just turn on the network and search and wait a few minutes that the receiver will need to scan and create a list of saved TV channels.

Tuning Channels on Legacy TVs

If desired, digital channels can be watched on an old TV, all that is needed for this. this is to manually configure the TV receiver and connect a DVB-T2 set-top box to it. Perhaps the only drawback of outdated TV models is a small amount of memory for storing frequently viewed channels, most often, no more than six positions can be added to this list.

To search and tune older TV models, you can use not only the remote controls, but also the physical control buttons on the TV itself.

Manual Channel Tuning

If the automatic tuning of TV channels does not work correctly, then you need to use the manual search option. With its help, the viewer himself decides which channels he wants to add to the saved list.

The algorithm of actions for manual configuration is as follows:

  • We turn on the receiver;
  • In the Menu, select “Channel Setup”. “Manual setting”;
  • Select the “Programs” command and assign numbers to them;
  • Additionally, you need to select a color system: PAL or SECAM, sound: 2.0 (stereo), 5.1, etc.;
  • We carry out the “Search” of channels and save the necessary TV channels.

The resulting list, if necessary, can be updated or deleted.

How to set up a new TV

In order to set up a new TV and connect it to a conventional antenna on the device, you need to select your native language. To do this, you need to connect the antenna cable to the successor, and then, by long pressing the “OK” button on the remote control, go to the Menu, where you select the LANGUAGE item. We mark the language RUSSIAN, after which all settings in automatic mode will be translated into Russian.

Why the automatic tuning of TV channels does not work

Modern TV models support both manual and automatic channel tuning. Most TV viewers use automatic search, which perfectly copes with the tasks, the user can only remove unnecessary channels from the list.

However, for various reasons, sensitive equipment is unable to recognize the scan range or signal source. In this case, the procedure must be carried out manually.

As practice shows, there are no particular advantages in choosing one or another method of channel tuning. And if the automatic mode is able to save the user’s time and is suitable even for inexperienced viewers, then the second option will require more time and special knowledge, but at the same time it provides more detailed channel tuning even with poor reception quality.

In especially difficult cases, you should use the services of a professional telemaster. The cost of his services will depend on the region of residence, distance from the workshop and the company’s pricing policy. In addition, today there are a number of volunteer organizations that help everyone to switch to a new broadcasting format for free.

Features of automatic channel tuning

How do I tune my TV automatically? To complete the procedure, you will need to perform the following sequence of actions:

  • We turn on the receiver, after which a message will appear on the screen stating that “Channels are not configured”;
  • Using the remote control, go to the Menu, where we select “Channel Setup”. “Automatic setup”;
  • Do not forget to indicate the type of broadcast. digital or analog.
  • Press ENTER / OK.

After completing all the steps, the TV will begin tuning channels by scanning the available frequency range. On average, Auto Tuning takes no more than a few minutes, after which all stored TV channels are displayed on the screen. In the event that nothing happened. don’t panic. We carefully study the instructions for the device. It necessarily provides detailed descriptions of the settings for this model.

In the event that the operator adds new channels, then the setting will have to be repeated using the edit option. In this case, the previously created list of TV channels is saved, new items are simply added to it. You can delete the old list using the appropriate command, after which you will have to perform a new search.

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, but there is no alternative to this.

A separate such device is installed in each room. 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, the presence of a TV in the house, which 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;
  • using two receivers.

Unacceptable connection option

There is a fairly simple method that allows you to connect two TVs to one satellite dish. However, it is unlikely that he will 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 RF 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.

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. Cases are common 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 to determine your TV model

Over the years, Sony has released a huge number of TVs of different models. Not all of them support digital reproduction, and among those that can do this, not all work with the European broadcasting standard DVB-T2. And first you need to define the model.

Adding local analogue TV channels

Although in Russia broadcasting of federal channels is being transferred to digital, analogue television is still preserved: local programs are broadcast on it. If you want to watch them, proceed as follows:

  • Go to the menu and go to “Settings”.
  • Select analog configuration (ATV).
  • Go to the item “Channel search”.
  • After the end of the procedure, guard the received analog channels.

Check if your Sony TV supports digital TV

Before you connect your digital TV and start setting up, you need to check if your TV can receive it at all. This can be done on the website of the manufacturer or official distributors of Sony products, but the easiest way is to use this online service. To do this, enter the model number in the “Search” line:

If your TV does not support digital TV

If it turns out that the existing TV receiver cannot independently receive a digital TV signal, the user has two options:

  • Buy a new TV. Given that television technology is constantly evolving, this is the most reasonable, but also expensive option. Some digital TV functions may not be available on older models (e.g. HD picture playback).
  • Install a digital set-top box (aka receiver, decoder, tuner). This option is good if the TV is relatively new and of high quality, but simply does not have a built-in digital tuner.

After the set-top box is connected, it also needs to be configured to receive.

Adding local analogue TV channels

Although in Russia broadcasting of federal channels is being transferred to digital, analogue television is still preserved: local programs are broadcast on it. If you want to watch them, proceed as follows:

  • Go to the menu and go to “Settings”.
  • Select analog configuration (ATV).
  • Go to the item “Channel search”.
  • After the end of the procedure, guard the received analog channels.

The channels were shown, but then they stopped

Sometimes it happens that digital channels that were only recently received suddenly disappear. What to do in this case?

But most likely the reason for the disappearance is the TV settings (for example, due to a power surge). In this case, it is recommended to use two methods:

  • rescan the range (in manual or automatic mode). It is possible that channels will be found;
  • full reset to factory settings (how to do this on a specific digital TV model, you can find out from the instruction manual). After that, you need to re-configure the TV receiver, including searching for channels.

Deleting and sorting channels

If for some reason you do not want to watch one or several found channels, you can delete them from the list. This is done as follows:

  • Open the menu.
  • Select “Settings”, then “Digital Configuration”.
  • Go to “Remove Programs”.
  • Find an unwanted channel in the list.
  • Hold down the central button on the remote control (“Select”, “OK”). The channel is removed.

In the event that you need to sort the order of the channels, the procedure looks like this:

  • Open the menu.
  • Select “Settings” and “Digital Configuration”.
  • In the menu that opens, go to the item “Sort programs”.
  • Enter the channel number to be changed and press the Select key. The program will stand out.
  • Use the “Up” and “Down” keys to move the channel to the desired position.
  • The procedure is repeated for all channels to be sorted.

Cable extension

If, for any reason, it becomes necessary to lengthen the television cable, then the easiest way to do this is using two F-nuts and an F-F-connector. Install the F-nuts as shown above and connect them with the F-F-connector.

Extending the cable with an F-F connector

TV cables

What to look for when buying?

  • The first is the outer diameter. It should be approximately 6.6 mm;
  • The second is shielding. The shield of a modern cable should be two-layer. a braid of thin conductors and a layer of foil;
  • The third is the insulation material. Modern cables are insulated with porous polyethylene. Better frequency response than solid polyethylene insulated cables.

Coaxial cable

Porous polyethylene insulation is produced in two ways: a cheap chemical, using a chemical reaction (this is what Chinese manufacturers sin with), and a more expensive physical one, when polyethylene is foamed with nitrogen gas under high pressure.

The frequency characteristics of coaxial cables with “chemical” and “physical” insulation are quite different. In addition, physically foamed coaxial cables are more stable and more resistant to environmental influences.

The type of insulation affects the frequency response of the coaxial cable

It is difficult for an inexperienced consumer to visually distinguish in what way the foamed insulation of a coaxial cable is made, so try to purchase products from well-known manufacturers from official distributors.

How to properly connect a TV to an antenna: we study circuits and equipment

To connect several TVs to one external antenna, you can use the socket antenna amplifiers or antenna splitters (splitters, “crabs”) described in the previous article.

Connecting TV plugs

Television equipment is usually wired with coaxial cable using F-type connectors (F-connectors). Their widespread use is due to the ease of installation and reliability of the connection, in addition, they provide protection against interference and external influences.

TV plugs with F-plug

The F-connector consists of an F-nut that is installed on the coaxial cable and a mating threaded part that is installed on the connector (TV-plug, F-F-connector) or equipment (amplifier, splitter, etc.).

F-nuts and F-F-connector

Step 11-12 mm from the end of the cable and carefully cut the outer insulation so as not to damage the braided shield (thin wires that cover the cable). Pull the braid and foil back and place along the cable. Strip 9 mm of internal insulation from the center conductor (see figure 1).

Remove some of the outer and inner insulation

Screw the F-nut tightly onto the cable, while the center conductor should protrude no more than 2 mm beyond the edge of the nut (see Figure 2).

Screw the F-nut tightly onto the cable

Now you can connect the F-nut either directly to equipment (amplifier, splitter, etc.) or to a TV or TV outlet using a TV plug. Connecting the TV cable plug

Antenna splitters (splitters)

To connect several TVs to one antenna, antenna splitters. splitters (“crabs”) are used. Splitters differ in the number of outputs and the type of housing.

Splitter with two outputs

The most common are molded case splitters for mounting on a circuit board. They are easy to place in a convenient location (for example, in a back box or behind a false ceiling).

In country houses, where a large number of receivers are provided, a special low-current shield is often installed for connecting and wiring telephone, television and computer networks. In this case, it is advisable to use modular splitters, i.e. for mounting on a DIN rail.

Left: modular splitter. Right: F-plug

When choosing a splitter, first of all, you need to decide on the number of outputs. The more there are, the weaker the output signal. For example, for a device with two outputs, the output signal level is reduced by about 1.7 times, and for a splitter with four outputs, by about 2.66 times. Therefore, the use of splitters with more than four outputs, as a rule, requires the installation of an additional TV signal amplifier.

Splitter with six outputs

The cables are connected via F-connectors.

Connecting the cable to the splitter

In addition, for the splitter to function properly, all of its outputs must be terminated. If for some reason one of the outputs is not used, a special F-plug (2) should be installed on it, in which there is a terminating resistor with a resistance of 75 Ohm.

Installing a plug on a free outlet

The high quality splitter has a die-cast housing, which is nickel-plated for additional shielding. The bodies of low-quality splitters are stamped already with a thread, and for high-quality ones the threads are cut after the final manufacture of the body.

Satellite TV

06/10/2009 How to connect a TV to a satellite dish

Connecting a TV to a satellite dish on your own is quite simple. The main desire and a little knowledge.

Here we will restrict ourselves to the specifics of installing and configuring a satellite receiving system for the Ku-band (10.7-12.7 GHz), in which all modern direct television broadcast satellites operate.

Choosing a location for installing a satellite dish

An open view from the point of installation to the satellite is required. All satellites are located in the direction from southwest to southeast. over, the satellites located right in the south are located most high above the horizon.

The elevation angles and azimuths to the satellites can be determined using the appropriate formulas.

where g1. longitude of the satellite, g2. longitude of the receiving site, v. latitude of the receiving site.

Any obstacles (most often houses or trees) on the line connecting the antenna and the satellite interfere with signal reception. In addition, the antenna should be in an easily accessible place for you, which is especially important at the time of its setup, and inaccessible to others, so that it cannot be easily damaged. Unfortunately, there are still acts of vandalism against satellite dishes.

Installation and installation of a satellite dish

Assemble the antenna according to the assembly instructions. Fix the support firmly at the selected point. When installed on a balcony or loggia, the fence is drilled through and the support is attached with ordinary long bolts of large diameter. When installed on a wall, holes are drilled in it and self-wedging anchor bolts are used.
When assembling the antenna, special care must be taken not to damage the parabolic mirror. Deviations from the shape of even a few millimeters lead to a noticeable drop in the signal level and deterioration of the image.
It is also important to position the feed of the converter precisely in the focus of the antenna. The position of the converter is usually determined by the design of the holder, but it allows for a play of several centimeters. The exact position of the converter can be determined experimentally by moving it in the holder while assessing the quality of the picture on the screen. This, of course, is possible if the converter is accessible after the antenna is installed in place, and does not “hang” in the air one and a half meters from the wall, being blocked from you by the antenna mirror. In this case, two ways can be proposed. You can find out the exact position of the converter from the seller of your system, or you can carry out a “training” installation in an accessible place and, having determined the exact position of the converter, move the antenna to the final selected place.
Sometimes it is important not only the exact installation of the converter in the focus of the antenna, but also the correct position relative to the axis of rotation of the converter. Typically, each converter (meaning converters monolithically combined with a polarizer and feed, which are used to mount the antenna on one satellite) has a “top” mark, which is associated with the position of the built-in polarizer (corresponds to vertical polarization). However, this mark should look exactly upward only at the geographic longitude of the satellite. If you install the antenna to the west or east than the satellite is located, then the converter must be turned in the holder around its axis. The effect is more noticeable, the further south (closer to the equator) you are and the further from you (lower above the horizon) the satellite is. Note that for many modern powerful satellites located not too low above the horizon, this effect can be neglected due to the margin of their signal power. However, if you are “catching” signals at the limits of your receiving system, then the correct angle of rotation of the converter can make a significant contribution to improving image quality.
This rule does not matter for converters designed to receive satellite signals with circular polarization, for example, for the popular NTV-Plus software package. There is no label on such converters, and you can install them in any convenient way.
Note that if you supplement your analog system for receiving satellite TV with a digital receiver, then your old converter may not work. Converters for receiving digital television are characterized by greater stability of the local oscillator frequency than older models designed for receiving analog signals. They are usually labeled “digital”. All converters produced now are suitable for receiving digital television. Converters without such an inscription, produced several years ago, may or may not be suitable for receiving digital television. If you have such a converter, then you can first try to receive digital signals on it. If reception is not possible, the converter will have to be replaced.

Setting the elevation and azimuth of the satellite dish

Adjust the elevation angle of the antenna, which is easy enough for centrofocal antennas (classic “dishes”). To do this, you can use a special goniometer or elementary devices. plumb line and protractor. Then use the compass to point the antenna in the azimuth direction.
It is possible to calculate the elevation angles and azimuths, knowing the orbital position of the satellite and the coordinates of the antenna installation point, using the formulas given in the footnote on the previous page, or using the SATTV computer program, which can be “downloaded” at: http: //www.telesputnik.ru / equipment / satTV.html.
Note that the exact presetting of the elevation angle for an offset antenna is a rather difficult task. The fact is that the offset antenna is, as it were, cut out of the paraboloid of revolution a little to the side of its center. Therefore, the direction coinciding with the axis of the paraboloid of rotation on the offset antenna, without knowing its design parameters, is virtually impossible to determine. For each specific design of an offset antenna, the angle between the cut-off plane of that antenna and the cut-off plane of the centrofocal antenna directed to the same point must be known. It is very difficult to measure it on a finished antenna, and you can usually find out only from the documentation of the antenna manufacturer.
It can be considered very roughly that on the territory of the former USSR, most types of polar antennas should be installed so that the cutoff plane of the antenna mirror is approximately vertical. The fact is that the elevation angles for the most popular satellites received in the European part of the former USSR are in the range of 20-30 °. And the characteristic angles for offset antennas, which we talked about above, lie in the same range.

The converter connects to the receiver with a coaxial cable. Please note that a piece of cable must be measured right away, taking into account the final path of its laying, with a margin for all bends and turns and possible movements of the TV inside your rooms. To connect the cable to the connector, the so-called F-connectors are used, which are put on the cable without soldering.
To tune, you need to be able to move the antenna vertically and horizontally at the same time and see the TV screen. Therefore, the equipment must be connected next to the antenna. If, for example, you are installing an antenna on the roof of a house, then this means that you have to pull out the receiver and TV on the roof and supply the mains power to them.
Ways to connect your analog receiver to the rest of your receiving set-up. The method of connection “at low frequency” using SCART connectors is considered more preferable. But if your equipment does not have SCARTS, then the “high frequency” connection is also quite efficient. The “high frequency” connection is also used in the case of splitting the signal to two or more TVs. Naturally, if the TV and receiver are removed to the roof, there is no need to carry a VCR there and connect an aerial antenna.
In the case of a high-frequency connection on the TV, you must select the appropriate decimeter channel for the receiver setting. When connecting “at low frequency” on the TV, select the AV (audio-video) mode,
If you connected everything correctly, then in the case of using an analog receiver, after turning on all the devices in the network, the characteristic noise of the converter should appear on the TV screen. Note that in many modern TV models weak signals (including converter noise) are covered by a blue screen.
After that, you need to set the frequency of one of the channels from the satellite to which you are tuning in the receiver.
In analog receivers with an on-screen menu (displayed on the TV screen), the frequency is usually set according to the values ​​shown in the table. For Ku-band. this is a five-digit number representing the frequency in megahertz.
If your analog receiver does not have an OSD, which is usually the case with cheaper models, then the frequency is fixed on the LED display on the front of the receiver. However, its value usually does not correspond at all to the value in the frequency table. The fact is that in this case, the so-called intermediate frequency is fixed on the receiver, which is the difference between the carrier frequency of the satellite television channel and the frequency of the local oscillator of the satellite converter. The converter lowers the signal frequency exactly to the local oscillator frequency in order to be able to transmit the signal over a coaxial cable without additional amplification for tens of meters. The local oscillator frequency is approximately ten gigahertz depending on the type of converter.
It would seem that everything is very simple. However, there are several types of converters with different LO frequencies (eg 10 GHz, 9.75 GHz and 10.75 GHz). Converters with two local oscillator frequencies are widespread, which are necessary to extend the receiving range of the system (for example, 10 and 11.75 GHz, 9.75 and 11.75 GHz). And in your receiver, this frequency may not be preset at all in accordance with the type of your converter. Usually the receiver allows one or another possibility of changing the frequency in accordance with the frequency of the local oscillator. Therefore, before setting the frequencies, you need to check the correspondence of these frequencies.
Let’s take a simple example. You want to tune your analog receiver to TV5 (Hot Bird satellite), 11.32 GHz frequency. Your receiver is factory set to subtract 10 GHz from the carrier signal frequency. And your converter has a local oscillator frequency of 9.75 GHz. You use the frequency table to determine the TV5 frequency, knowing the frequency of the local oscillator of your converter, set it to 11.32 on the receiver display. 9.75 = 1.57 GHz and you don’t see any TV5 channel since your receiver is actually set to 1.57 10.00 = 11.57 GHz.
This means that you need to change the 10 GHz frequency to 9.75 GHz in the receiver. There are some receiver models that do not allow such a replacement. In this case, the correction 10.00.9.75 = 0.25 GHz will have to be made mentally without the correct display of the numbers on the display. In the case of a dual-band converter, which has two different local oscillator frequencies for different frequency ranges, the situation can become significantly more complicated.
For a digital receiver, the connection diagram is exactly the same. No converter noise will be visible on the TV screen. Just a dark screen will appear. The complex situation described above with the frequencies of the converters is not typical for digital receivers, since they all have an on-screen menu and usually allow you to set the necessary frequencies of the local oscillator of the converter.
If you supplement an analog system with a digital receiver, then the connection is made as follows. From the converter, the signal is fed to the input of the digital receiver. From the output of a digital receiver, made for a standard F-connector, you send a signal to the input of an analog receiver. Such an output in different models of the receiver may be called differently. LOOP-OUT, LBAND-OUT or something else. Usually in its name there is the word OUT. In this case, if the digital receiver is turned on, and the analog receiver is in standby mode, then you are watching digital programs, and, accordingly, vice versa. If your TV has two free input SCART connectors, then it is better to connect both receivers through them. If only one SCART is free, then an analog receiver can be connected at a high frequency. This only has the inconvenience that when switching from digital to analogue mode and back, you will have to switch the TV from normal mode to AV mode and vice versa.
However, some digital receivers do not have such a “pass-through” output. Then we can recommend splitting the signal from the converter to the inputs of both receivers through a divider by two. This is a very simple and cheap device, and you can buy it in the same place where you buy other equipment for receiving satellite television. Please note that this should be just a “satellite” divider, not a divider for terrestrial television signals. Outwardly, they are not much different. The difference is that the “satellite” splitter allows higher frequency signals to pass through. up to 2 GHz. In addition, a two-way divider will halve the signal level fed to each receiver (by 6 dB). That is, your receiving system must have a signal margin. antenna slightly larger than the minimum required for a given satellite.
Recently, quite a lot of models of combined digital-to-analog receivers have appeared, which allow receiving digital and analog signals to one device. They usually have two separate entrances. digital and analog. In this case, we can also recommend using a divisor by two. In addition to the frequency, two more parameters must be configured in the digital receiver. the bit rate SR (symbol rate) and the FEC parameter, which characterizes the level of error correction in the digital stream. These parameters can also be taken from the table published in our journal.

Final tuning of the satellite dish

Tighten the screws that adjust the movement of the antenna in the azimuth and elevation directions so that you can move the antenna up and down and left and right with some effort, and without applying force, the antenna would remain stationary. After that, start systematically scanning the sky around your chosen aiming point. If you use an analog receiver and have followed all the previous points correctly, then in the end you will be able to “catch” a noisy TV signal on the TV screen. After making sure that you have caught the satellite you need, and not one of the neighboring ones, perform a “fine” adjustment based on the quality of the TV picture.
A signal level meter can be useful here. the so-called “satmeter”. However, if you don’t have one, don’t be discouraged. In most cases, for the most popular satellites, the antenna can be perfectly tuned without it.
Note that it makes sense to carry out the coarse tuning on the most powerful channel, and the final fine tuning. at the weakest. After making sure that it is impossible to improve the picture, finally tighten all the fasteners on the antenna, lay the cable from the antenna to the viewing place and install all the equipment in the rack under the TV.
In the case of a digital receiver, this operation is much more difficult. The fact is that analog reception has a very wide range of input signal levels. from when something becomes visible through the interference to perfect reception. over, the analog receiver works out the change in the input signal instantly, changing the picture on the screen accordingly. Digital reception is characterized by the threshold nature of the appearance of the image. The transitional stage, when the image shakes and breaks, has a very narrow range of input signal levels. The situation is further complicated by the fact that the digital receiver does not instantly “capture” the picture. Even with a sufficient input signal, it takes a few seconds to process the image.
Therefore, you can offer the following options for setting up a system with a digital receiver. First, you can borrow an analog receiver somewhere for setup. On the most popular satellite constellations such as Hot Bird 1,2,3,4,6; Eutelsat W4 / Sesat; Astra-1 B, C, D, E, F, G, H, 2C; Thor-2,3 / lntelsat-707, both digital and analogue television channels currently exist. After tuning the antenna “by analogy”, you can connect digital equipment.
If there is nowhere to take an analog receiver, then the option of adjusting the signal level meter remains. It should be remembered that the satmeter can be connected to the converter with a length of cable no longer than a few meters. With a cable of several tens of meters, the satmeter “does not pull”. Most models of modern digital satellite receivers have a built-in digital signal level meter. Although these are rather crude meters, they can greatly facilitate the setup process.
When adjusting by signal level, accurate azimuth adjustment is of particular importance. Satellites in geostationary orbit are located several degrees apart. Therefore, tuning in the signal level to the wrong satellite and setting the parameters of the digital signal (frequency, SR, FEC), you will not see anything, and it will be very difficult to understand what you have tuned incorrectly.
The receiving satellite installation with a positioning system for different satellites will significantly expand your capabilities. Such a system allows you to receive up to 100 or more analog channels and even more digital.
Consider an antenna design that can tune to multiple satellites. Such an antenna is characterized by a suspension design called “polar”. This suspension was invented for astronomical instruments and has such a name, because the axis around which the antenna mirror rotates is parallel to the axis of rotation of the Earth. And she, as you know, is aimed at the North Star.
In the suspension configuration, the elevation angle of the polar axis is approximately equal in absolute value to the geographical latitude of the antenna mounting point. The “approximately” correction arises due to the fact that the Earth does not have an ideally spherical shape, but is flattened from the side of the poles. The elevation angle is selected based on the directivity of the antenna axis parallel to the equatorial plane. To rotate the antenna axis towards the satellites in geostationary orbit, the so-called correction, or the angle of declinations, is used. From the simplest geometric considerations, it is clear that these three angles add up to 90 °.
