Abstract (en)
Method and apparatus for transmitting a plurality of control signals to an antenna system, in particular for directly receiving television signals from satellites, by means of the radio frequency transmission cables (16) of the system. The apparatus comprises at least one receiving antenna (1,5) having actuators, a low noise converter/amplifier (4, 7), a transmission cable (16), at least one internal unit (21,22), first circuit means (100) for transmitting codified signals in said cable and second circuit means (200) for receiving and decoding those codified signals, for sending adapted electric signals for operating said actuators. For generating receiving and decoding those signals, integrated circuit are used of the type currently employed in remote controls for TV sets, electric gates and similar devices.
