TV amplifier

An antenna amplifier is one of the most important elements of a broadcast system, necessary to improve the quality of the signal when located at a significant distance from the broadcasting repeater or when communication with the satellite is unstable. It has a directed effect on changing the frequency of the wave received by the antenna with subsequent transmission to the appropriate equipment. In addition, these devices can perform the additional function of a splitter - dividing the signal into several streams to display the image on different TV screens.

The range of amplifiers on the market does not enjoy such high popularity from famous manufacturers, and, therefore, does not have a huge number of models sold. However, the whole problem with choosing a good device rests on basic ignorance of the main criteria, which is why purchases very often turn out to be in vain. Therefore, after carefully researching this segment, we have compiled for you a rating of the best amplifiers for digital and analog television, which are very popular among domestic users.

DIY antenna amplifier

You can design a simple device that amplifies your TV signal for your TV with your own hands. This device has low power consumption, does not create significant interference, and has a frequency range of up to 900 MHz. A low-voltage amplifier with a power supply of 2.7-5.5 V consumes a current of 3 mA and operates very quietly.

The operating principle is as follows. Voltage is applied to input “1”, which is shown on the microcircuit. Thanks to resistor R1, a bias is created in the working area. It is connected to input "2". The input signal comes to output “6”, while the amplified one is removed from node “3” and sent to the receiver. If the chip is assembled correctly, there is no need to configure it. By the way, you can also make an antenna for a TV yourself.

Various factors can negatively affect the TV signal level. Modern radio technology devices help to increase it. They have a number of advantages: mobility, high gain and a large selection of models. Thanks to the joint work of the antenna and amplifier, you can watch television in good quality.

Overload protection and indication are also provided. LTE signals are suppressed by a special built-in filter. Band splitting is provided with separate gain and slope adjustments in the VHF (47-414 MHz) and UHF (470-862 MHz) bands. The device can operate in the cold (-20°C) and in the heat (+50°C). Power consumption is low and is only 5V.

Price: from 3,200 to 3,780 rubles.

• wide temperature range (from -20 to +50°C);
• there is a special filter that suppresses LTE signals;
• the presence of “ears”, thanks to which the device is mounted on the wall with ordinary screws or bolts.

• not detected.

I bought this miracle piece of technology two weeks ago, and I already have some impressions that I want to share. The model has one input, but inside the amplifier the entire range of the television signal is divided into two subranges: MV and UHF. In each of the sub-bands there is a gain and frequency response slope adjustment, two attenuators and a stepless gain and frequency response slope control. The output signal is formed by summing the signals from the VHF and UHF subbands of the amplifier. The case is strong, moisture-resistant and beautiful.

Terra HS004

Alcad AL-200

The wideband residential amplifier from the Spanish company Alcad is one of the most popular on the Russian market. It is highly reliable and is designed to amplify television signals in the UHF and meter wavelength range; it has one antenna input and two outputs. Typically used to distribute a television signal to several televisions in a house or apartment. The device also has separate gain controls for the MV and UHF ranges, ranging from 0 to 15 dB. The amplifier operating frequency range is from 47 to 860 MHz.

Good afternoon I recently purchased this amplifier model for my TV, which has been receiving a poor signal lately. Overall it was more than helpful. There is separate adjustment for the MV and UHF ranges. Factors such as high power (gain up to 24 dB) and low noise level encourage the purchase. It is one of the most effective solutions for amplifying the signal received by one antenna for the whole house. Fully compatible with the DVB-T2 standard.

Alcad AL-200

Rexant 05-6202

A television divider is a convenient means for dividing a signal into several equal parts. Antenna splitters, also called television splitters, are used in cases where it is necessary to connect one television cable coming from the antenna to several televisions or receivers at once. This is especially true in multi-room apartments or country houses. The divider has one input for an F-connector and three outputs also for F-connectors. The signal supplied to the input of the divider is divided into two equal parts and transmitted to the outputs. Standard F-connectors are used to connect cables.
