The TERRA HA126 is a professional cable TV amplifier designed to amplify and distribute RF signals in cable television networks. With a gain of 34 dB, it is suitable for installations where signal losses over long coaxial cable runs and distribution networks need to be compensated for.
The amplifier operates across the 47–862 MHz frequency range and features built-in gain and slope controls. These adjustments allow the signal to be optimised for the requirements of the cable network.
