Today it is the largest Russian supplier of high-quality digital television. But, despite the demand, many users quite often encounter such a problem as lack of signal. Quite often, many users need to improve the quality of the signal from Tricolor TV. If such a malfunction occurs, there is no need to panic. Most often this happens due to the lack of a signal, and as for the reason, many users already intuitively guess what’s going on and try to correct the situation on their own.

Reasons for a weak signal

So, let's take a closer look at how to identify the cause of a bad signal and how to improve the quality of the signal from Tricolor TV.

In order to improve the signal quality, you must first determine the cause. Conventionally, all problems associated with a poor signal can be divided into two main groups:

1. External reasons. It is worth noting that they do not depend on the user's receiving equipment.
2. Internal problems. They are associated with malfunctions in the operation of the subscriber’s equipment itself.

Users are trying to figure out for themselves what determines the quality of the Tricolor signal. For example, external reasons include any weather conditions, such as strong wind, snow, rain. Also, the signal may disappear due to various restoration work in case of accidents.

Why does the TV signal deteriorate?

The TV signal is distributed from the towers of local branches of the Federal State Unitary Enterprise "Russian Television and Radio Broadcasting Network". In 2018-2019, the unitary enterprise installed additional reinforced concrete supports in cities and villages for digital broadcasting.

Television uses a wide range of frequencies, this is fraught with 2 reasons for the deterioration of the television signal:

• Both digital multiplexes distribute through a single antenna-feeder network, which is more suitable for certain radio frequencies. The channel packages themselves can be broadcast with a significant frequency difference. In this regard, the coverage of one multiplex is noticeably better than another.
• Some receiver configurations may not be suitable for specific frequencies. For example, a cheap Polish antenna purchased may not pick up a digital signal due to the incorrect length of the pins on the array.

In addition to the above reasons, deterioration of the television signal can occur due to:

• Obstructions between the receiver and transmitter. Even capital construction projects or terrain can become a potential obstacle.
• Malfunctions of the receiving equipment - broken cable, damaged antenna array, burnt amplifier or TV connector.
• Disabling a previously operating transmitter. Over the past year, Russian regions have almost completely switched off analogue television broadcast transmitters.
• Transmitter maintenance.
• Interference - this happens extremely rarely. If you suspect interference, write a statement to the nearest branch of the territorial Office of Roskomnadzor. Department specialists must respond to it and take measures to eliminate the problem.
• Incorrect azimuth of the directional antenna array.

FSUE "RTRS" separately transmits sound and picture for an analog television signal. Digital multiplexes transmit using a single spectrum.

Some of these problems can be solved without spending money - by correctly rotating the antenna or contacting the federal service. If there is no reception due to a weak TV signal, a properly selected amplifier will help.

What to do if the signal is lost

Not all users know how to improve the signal quality from Tricolor TV. There are also problems that are not at all related to the operation of the satellite dish; the TV itself produces such an error about the absence of a signal. In order to find out the reason why the channel does not work, it is first recommended to configure the TV itself. In order to do this, you need to press the “Ok” button on the Tricolor remote control. After these manipulations, a list of channels should be displayed on the TV screen. If this does not happen, it means that the settings of the TV itself have gone wrong.

In order to troubleshoot problems, you need to configure the TV again; to do this, you need to select the input for connecting the satellite receiver.

After this, you need to disconnect the signal receiver from the power supply for about one minute. Then you will need to turn on the receiver again, and all you have to do is wait for the signal to appear.

If the signal still does not appear, that is, the situation has not changed at all, you need to double-check the number of channels on which the “No Signal” record is still stored.

In situations where the error does not persist on all channels, but only on one, in this case, as a rule, it is enough to just update the channel list.

To increase the quality of the signal from Tricolor TV, you should perform a number of manipulations:

1. Select “Menu”, then click on the “Ok” button.
2. Next, a message about updating the channels will appear, you must agree and click on the “Yes” or “Ok” button.

It may take some time for the channels to update. Therefore, if the update is not completed yet, there is no need to worry. If after the update the problem was not resolved, that is, the signal did not appear, in this case the reason is related to the operation of the equipment itself.

Lack of signal on Tricolor TV due to maintenance work

In order to increase the quality and strength of the signal from Tricolor TV, it is imperative to perform a number of specific actions, the correct implementation of which can give a 100% result.

Before finding out what exactly the problem is, it is recommended to check the natural reasons why the channels are missing. It often happens that the signal is lost when various maintenance work is carried out. As a rule, subscribers receive notifications about such scheduled work several days before they begin, so they should not be ignored. Or if such SMS notifications do not arrive, there is another way to find out about maintenance work - go to the official website of the provider.

If, nevertheless, no information about preventive work was received, therefore, the reason for the lack of signal is different. Now it remains to determine the true reason for the poor quality of the signal from Tricolor TV.

Technical problems of no signal

First, it is recommended to check the cable connection from the receiver. To do this, it is recommended to perform a number of specific actions:

1. Check the cable for any damage or breaks.
2. Check the tightness of the contact threads.

A visual inspection can reveal whether there is obvious damage. If there is no visible damage, then in this case it is recommended to check hidden problems using a tester.

If the problem is a damaged cable, then it needs to be replaced. If it is not possible to completely change it, it is recommended to eliminate the break points and connect the cable parts together. For these purposes, you can use a special connector with two F-connectors.

What to look for when choosing a cellular booster?

Stay up to date! You should pay attention to the following parameters:

1. Frequency. The most popular base tower bands are 900 MHz and 1800 MHz. In terms of range, the tower with the first indicator wins, but the second can serve more subscribers. Therefore, according to established practice, it is optimal to use 900 MHz stations in rural areas, and 1800 MHz towers in urban villages and cities. In the country - 900 MHz, in the apartment - 1800 MHz. Don't get confused!
2. Gain. Here you need to take into account the operating features of your mobile phone. It is not recommended to buy a device with a coefficient of 65 dB or lower: the connection quality will be frankly weak. Does your mobile phone work well outside, but worse at home? Buy a product with a reading of 70-75 dB.
3. Output power. A power of 100 mW covers about 200 square meters. - start from this.
4. Antenna. On the outside, the material is especially important, because this device must withstand both wind and precipitation. The best material is aluminum, coated on top with a special protective paint. For internal antennas, appearance is not so important: they are usually hidden under finishing materials. If there are several antennas, you will get a more stable signal. But in this case, you will also need power dividers (they distribute the signal evenly between rooms and provide better coverage).

Important! 4G repeaters are not dangerous to human health, on the contrary: they reduce radiation. And the consent of any services is not required.

What needs to be done for this

To improve the quality of the signal from Tricolor, it is recommended to perform a number of actions:

1. Cut the cable right where the break was detected.
2. Strip the cable from the braid.
3. Screw the connectors onto the cable.
4. Secure these connectors using a connector.
5. Next, you need to strengthen the connection; to do this, you need to wrap a layer of electrical tape over this connection.

In situations where the cable is not damaged, it is recommended to check the tightness of the F-thread.

The quality of the signal from Tricolor TV may also depend on the receiver. For example, if the receiver is faulty, there will be no signal. And in order to find out, you need to connect it to a working antenna. To do this, you can ask one of your friends or neighbors for a working antenna from Tricolor. If a signal appears when connecting someone else's antenna, then the cause of the breakdown is a non-working antenna.

If you install someone else's antenna and there is still no signal, then the receiver is broken. Quite often, it is the tuner that is responsible for receiving the signal that fails. Not many people will be able to repair the receiver themselves, so in this case it is best to immediately take the receiver to a service center for repair.

The best budget antenna amplifiers

Remo BAS – 8102 – 01

In terms of compactness, it has no equal. The price tag looks nice. The main disadvantage is that it is almost impossible to purchase in specialized retail outlets. The order is carried out mainly through an online store selling antennas and all kinds of accessories. Only large domestic retail outlets such as M.Video and DNS please customers.

It is extremely popular among specialists in this field. But there is no need to talk about his impeccability.

In its appearance and size it resembles a USB flash drive, inside of which there is a tiny board. Despite its size, it is able to amplify the signal at a level of 16 dB. This is a stated figure, although in reality it is not true. It will be a completely useless device if the tower is located a hundred kilometers from the house. There is no gain control at all.

For the product to function, you must have a power supply with a USB connector. This device is included in the kit and there is no need to purchase it additionally. If there is a USB socket on the TV, it makes it possible to power the device from it.

The amplifier is broadband, operating at a frequency of 48.5 - 862 MHz. Supports digital TV channels. The noise level is less than 3 dB, which is considered an excellent characteristic. The output and input impedance corresponds to a value of 75 Ohms. You will not be able to connect a second TV to the device without additionally purchasing a divider. The build quality is a big question.

According to users, the main disadvantage is that some models are produced with the central wire of the coaxial output not soldered to the board. If such a situation arises, there are two options: either return the low-quality product to the seller, or disassemble the product and solder a small wire on your own. But even after performing such manipulations, the product may stop working if it is constantly removed from the USB port.

The purchase price is 550 rubles.

Remo BAS – 8102 – 01

Advantages:

• simplicity in use;
• presence of a power supply in the set;
• acceptable price;
• power supply is provided directly from the TV;
• low noise level;
• able to support a significant number of frequencies.

Flaws:

• in most cases the assembly is of poor quality;
• the plastic used is of poor quality;
• the signal gain is insufficient;
• lack of signal division capability;
• lack of signal gain adjustment.

Antex AX – S 20 U

A miniature amplifier with a different design. Wires with a specific resistance are not provided. It looks like a small box with input and output connectors on the sides. There are no difficulties with use; even amateurs have no questions. The main drawback of the product is the lack of a cable to connect the amplifier to the TV. You will have to purchase it yourself.

Despite its minimal dimensions, it is able to produce a gain of 20 dB. He copes with the assigned tasks with a bang. The noise figure is 3 dB, which is good news. An ideal purchase for those people whose apartments are located at a significant distance from the tower. It works with one TV, if there is a need to connect several more, it is worth purchasing dividers, which will negatively affect the operation of the device and can reduce its functionality to nothing.

Electricity is supplied through the use of an antenna input. In order for the product to start functioning, you need to purchase an AX-TVI USB power injector from a specialized retail outlet. This question will arise if the family does not have the latest generation TV with the ability to supply five-volt electricity to its own antenna input. Most digital set-top boxes have this functionality and are able to receive a signal in the DVB – T2 format.

The model has the ability to amplify the signal in the frequency range from 470 to 862 MHz. This suggests that you can watch digital TV in stable mode. But the device is not designed for a larger device.

The product is sold at a price of 500 rubles.

Antex AX – S 20 U

Advantages:

• build quality;
• compactness;
• presence of high gain;
• value for money;
• designed to amplify the frequency of digital TV;
• the manufacturer will equip the device with protection against voltage surges in the electrical network;
• ease of use.

Flaws:

• there is no gain adjustment;
• There are clearly not enough connectors;
• power supply is provided exclusively via the antenna cable (in a strictly established volume of 5 volts).

Remo USSH – 5 V

It is considered the most budget option. Its parameters resemble a regular adapter. Consists of two structural elements:

1. An amplifier equipped with an input for a cable that extends from the antenna. The body is made of black plastic. There is a microchip inside.
2. Elementary plastic F – white plug. Inserts into a special socket on the TV.

The elements are connected to each other with a short-length wire (up to 10 cm). It is easy to use. It is enough to connect the device to the TV, and then attach the antenna. The second action may cause some difficulties. It all comes down to different sizes of connectors. If you accidentally snag the wire, the plug will quickly jump out of the socket. This situation arises if you come across a low-quality model.

The device parameters are insignificant, but the signal amplification occurs at the proper level. Many users note an increase of 10 - 15 percent. There are no cases where the device did not produce any effect. There is an exception to the rule. It concerns the situation in which the existing antenna is already equipped with an amplifier. In this situation, the products will not function.

Broadband model. Supports frequencies in the range from 48.5 to 862 MHz. Designed for watching digital television. The manufacturer does not provide a separate connector for electricity, which is a significant drawback. Therefore, the device will only function with a TV or set-top box that is able to provide power to its own antenna connector. But the product does not need a network adapter.

You can purchase products at prices ranging from 250 to 370 rubles, depending on your region of residence.

Remo USSH – 5 V

Advantages:

• compact parameters;
• a budget option;
• stability of maintaining digital TV;
• amplification quality;
• practicality;
• simplicity in use;
• marriage practically never occurs.

Flaws:

• antenna output in one copy;
• Gain control is not provided by the manufacturer;
• The antenna cable must provide strictly 5 V power.

What actions need to be taken

In order to fix this, you need to perform a number of specific actions:

1. Prepare wrenches in advance: they may be needed to tighten the nuts.
2. Carefully inspect the place, try to eliminate all possible sources of danger.
3. It is recommended to tighten all antenna connections.
4. Set up the antenna. That is, point the antenna in a certain direction until a clear signal appears.

Each time you change direction, you need to take short breaks, about 5 seconds. It is best to get someone's help during setup. That is, one person adjusts the antenna, and the other checks the signal quality.

The signal quality can also be checked by pressing the F1 button on the information channel. In the lower left part of the screen you will see a signal strength scale and a quality scale. This figure must be at least 70%. If the indicators are higher, the setup work can be stopped.

If it is not possible to adjust the antenna yourself, you must use the services of a specialist who will adjust the antenna using the horizontal scanning method.
