All known in physics course that any signal fades with time, so the further the subscriber from the signal source, the signal becomes weaker. This leads to what appears on the screen noise, the image may be blurred, jerky, or in the worst case, the screen you will see a snowflake. The same story is with cable TV, which has a number of negative factors affecting it. Far distance, bad cable, a weak transmitter, radio interferences and noise, and more.

In all these cases, the main and the only solution would be the use of special signal amplifiers.

Thus, a special console will be able at the program level strengthen the signal and improve its technical characteristics.

In order to get into the catalog television signal amplifiers First you need to go from the main page of the site to the complete list of all sections. After that, all the list find the section " Consumer electronics"Where to choose the following category" Homemade audio and video". After that, in the window that opens, you need to choose " TV receivers", and then " Television antennas". After that, use the search for the keys and enter there " amplifier". Thus, you can see the full list of all amplifiers TV antennas.

In this directory, you can choose for yourself the most optimal option. television Amplifierthat offer all sorts of sellers and shops. Each of these goods has its own specific features and specifications that directly have an effect on the quality of the output signal.

TV amplifier

Television amplifier Used so that the receiving antenna will work better and to improve the quality of the received signal. This is a prerequisite in the event that there is a sufficiently large distance to the television center, where the signal fuses significantly in space. Also the need for use TV amplifier It may be if the receiving antenna is in the TV insufficient good quality.

Otherwise you can formulate that television amplifier Gets a bad signal, enhances it and improves, and then transfers to the TV is significantly better. The most popular use amplifiersit happens on the lower floors of high-rise buildings, or which are at a significant distance from the radio transmitting tower.

In order to correctly pick up television amplifier It is necessary to possess some data:

• approximate distance to the transmitting television antenna;
• have information about the required frequency;
• know the type of antenna that is installed and connected to your TV.

These all data will certainly allow to make the right choice and consult with the store's seller that can give a good advice on the most appropriate model. TV amplifier.

antenna amplifier

Television amplifier It is recommended to install not far from the antenna, but in a place protected from all kinds of precipitation. If antenna amplifierinstall near TV, noise from amplifierwill create interference in the image. Thus, you will not get a high-quality image without distortion.

If we talk about nutrition like amplifiers, you often use small currents in the antenna cable itself. For connecting antenna amplifier A coaxial cable is used, it has a substantially low loss coefficient by which the signal is transmitted to the smallest attenuation. Some amplifiersfor antennas, they have built-in protection against electromagnetic interference, because they are not terrible, adverse conditions and all sorts of third-party tips.

Often amplifierinstall when the TV is removed and the receiving antenna, on the distance from the transmitting the tank more than 20 km. At the same time, the distance can reach about 100 km. The further antenna is distant, the more powerful it is necessary. amplifier.

Also do not choose amplifiers for antennas With a large gain, since greater gain can produce self-excitation and publish unnecessary noise in the image. When choosing the right one antenna amplifier It is necessary to know the measure of strengthening, since the bust can adversely affect the signal quality.

signal amplifier

To date, special tables have been developed that greatly facilitate the correct selection of a television signal amplifier for a home antenna. Therefore, knowing the conditions for reception and other information about the antenna, it will not be difficult to choose the right model with certain enhancement characteristics.

Often install the antenna broadband amplifierwhich is able to capture the entire range of television broadcasting. Often this way and come when choosing and purchasing amplifier signalin the catalog world famous trading platform Aliexpress.

Also, if you wish, you can choose this type amplifierwhich will be designed to work both at a closer distance to the transmitting antenna and for far. This will allow you to purchase exactly such amplifierwhich will be optimal for your needs. If there are several TVs that host the ether television signal, then instead of acquiring several amplifiersyou can use this type that allows you to transmit a signal on various cables.

For example, if an antenna is installed in the apartment in the form of a lattice, then when choose amplifierfor her, it is necessary to take advantage of the such noise as possible. In this case, it is impossible amplifierhave high gain. Wherein amplifierit is selected by the method of selecting the necessary gain.

antenna for television

Antennas for televisions - This is one of the main elements when receiving airtal television. A large number of structures allow you to receive a signal in different ranges, whose oscillation frequency is significantly fading during the passage of space.

Thus, the antenna must be selected as correct as possible to get a better picture on the TV. When installed antennasall specifications should be understood as a range of television transmitting antenna, possible obstacles on the path of distribution, as well as the frequency range.

Thus, it is possible to choose the optimal option. antennasfor your TV, so that the picture on the display was not only a clear, but there was no distortion and noise.

digital amplifier

To date, digital television develops, which allows you to transmit a large number of different channels on one signal at one frequency. This is due to the signal encoding, while the quality of digital television is significantly better than analog. The digital signal is also transmitted along the air channel, therefore there is a need to accurately enhance the digital signal, as is the analog.

Digital channels are also accepted for conventional antennas, after which they are transmitted to a special device - a receiver where it is decoding. Many have come across the problem when due to bad weather, or long-distance from television center was a bad signal, and some channels were absent at all. In order to restore them need to use the special digital amplifier.

Digital amplifier For television DVB-T2 compensates for the signal loss and eliminates excess noise in the image, and in order to connect it to be installed before entering the receiver. It is very convenient that the digital amplifier requires a small amount of current, which is enough to work the amplifier from the receiver itself.

In catalog Aliexpressyou can easily select the most optimal digital options. amplifiersfor television.

Customer Reviews Price-Quality

M *** A M.Thanks to the seller for support and help in acquiring quality amplifier. Acquired for cottages, because It is 50 km from the city. An ordinary directional antenna was installed, but the noises were very strong. Yes, and many channels simply were not and did not even work out. With a new amplifier, I achieved a stunning effect. Those channels that were already - began to show better, and many others appeared - new ones. Recommend

R *** L V.We live on the first floor, because not the first time we face the situation when the signal disappears simply. This is especially affected when it goes on the street. The image is snowing so that sometimes drives crazy. On cable television there are not all channels that are shown on the air. Therefore I had to purchase such a wonderful thing on Aliexpresslike a signal amplifier. Thanks to a large seller. I advised friends to buy goods.

C *** R S.Good afternoon, dear seller. Unfortunately, your toy was just useless in our conditions. May be far from the transmitting tower, maybe for some reason. Let us try to give familiar to the village, maybe they will earn properly. I still put 5 stars and for pleasant communication, and for fast dispatch, respectively, and delivery. Good luck.
