Correcting amplifier for cable TV
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.
