PURPOSE:To attain the selective output of common reception signals to objective two terminals by providing a branch structure which selectively outputs the signals that are amplified in an amplifier circuit in a housing to optional two branch output terminals out of four. CONSTITUTION:The common reception signals which is supplied. A main line input terminal 6 are amplified in the amplifier circuit 21 and are outputted to a main line output terminal 7. With the operation of a switch in the branch structure, the signals are selectively outputted to two branch output terminals 8 and 10 on one side wall, two branch output terminals 9 and 11 on the other, or to each branch output terminal on one and the other side wall. Thus, the common reception signals which is supplied the main line input terminal 6 are amplified and they can be outputted to the main line output terminal 7. The signals can selectively be outputted to two objective terminals out of four branch output terminals 8-11.
