For example for the amplifier with an amplification factor 24 dB, cables type РК-75-7-12-75-7-12 and РК-75-7-15-75-7-15 in a meter range to 220 MHz the losses are compensated through attenuation to 160 m, in a decimeter range to 750 MHz - in the distance to 60 m. In cable of type РК-75-7-11-75-7-11 in a range to 220 MHz - in the distance to 250 m, and in a range to 750 MHz - in the distance to 90 m.
