ANTENNENSTECKDOSE

1. An antenna socket, particularly for fitting on a wall of a building, having a first coaxial socket connector (2) for the output of TV-signals, a band-stop filter (6) for radio signals whose output is connected to the first coaxial socket connector (2), a second coaxial socket connector (3) for the output of radio signals, a band-pass filter (7) for radio signals whose output is connected to the second coaxial plug connector (3), a first terminal (1) for a coaxial cable for the supply of antenna signals, a second terminal (4) for a coaxial cable for the forwarding of antenna signals, and a directional coupler (5) in the form of a line coupler (5') or a repeater coupler (5") whose through line input is connected to the first terminal (1), characterised in that in order to feed return channel signals to the central control of a cable television system, the through line output (10) of the directional coupler (5', 5") is connected to the inputs of the band-pass filter (7) and the bandstop filter (6), and that the output (11) of the coupling loop of the directional coupler (5', 5") is connected to the second terminal (4).
