Mains powered amplifiers to amplify satellite signals with passive loop-through of the TV signal. To be used as a launch amplifier in IF systems or as a SAT line amplifier. They allow gain and slope adjustment in the SAT band. Cover fixed with safety screws. No DC pass from the output to the inputs. Compatible with DTT signals in COFDM modulation. For installation, supports are available (item MBX0001, see page 64) that leave a space of 19mm between the amplifier and the wall, allowing room for cables or the amplifier to be mounted in different positions.
