Abstract

In the output circuit and the interference filter (100), the feed current of the amplifier (5) of the captured signals of the receiving element (4) is sent through a line (8) which is connected to the centre line (20) of the coaxial cable (3) which forwards the signals from the amplifier to a receiving unit (6). In the output circuit (100), which is earthed by its conductive container (1), a capacitor (10) is mounted on the centre line (20) of the same cable which provides for the forwarding of the amplified antenna signals but which, however, also stops the feed current and does not allow it to reach the receiving unit (6).
