This amplifier is designed to compensate for losses in the cable trunk. Its frequency response is inverse of the attenuation in the cable. So at the end of a 150 m cable type SWТ-1M is loaded by a resistance of 75 Ohms is connected to the output, the level of frequency 200MHz = +6 dB, and the level of frequency of 50 MHz = +2 dB relative to the linear input of the amplifier. The total response of a linear R9 are putting for a specific length of cable.

The amplifier can also be used as an antenna or a house, for meter waves.
