Satellite reception antenna arrangement

摘要

The antenna arrangement for satellite reception has an antenna reflector with a reception converter (6). The latter is driven by a control motor (1) and is arranged on the rotor (3) of a spindle drive (2,3) and connected to the playback device (7). A reception control element is provided between the converter (6) and playback device (7). The control element includes a memory member (5) to store different positions of the converter (6) allocated to different transmission frequencies. It also includes an actual value receiver or generator (14) and analysing electronics (8). The output of the reception control unit (4) is connected to a regulator (1a) for the control motor (1). Its input is connected to a signal generator (9) which delivers a control signal when a programme is selected. The control signals trigger respective control sequences to determine the actual position of the converter (6). This is compared with a stored target position and the difference is used to control the motor regulator (1a).
