摘要

The blocking box (1) has an antenna connector box with at least one connector socket (3a,3b) and a clamp plate (7) for attaching a connection cable which can be switched to the antenna connector cell. The connection socket is electrically and/or optically isolated so that no output signal can be extracted from it and the clamping plate is secured against unauthorized removal. A circuit board connects an incoming connecting cable (8a) to an outgoing connecting cable (8b).
