  • Change-over switch of external units of fixed aerials for satellite signal receivers
    Patent number: 7912420
    Abstract: For individual reception of signals of television, radio and other services provided for by means of geostationary telecommunication satellites there is designed a change-over switch of external units of fixed aerials with a system of individual switches controlled by means of standard pulses generated by a satellite receiver. The change-over switch is provided with a command decoding unit (7), having an input (71) being connected to an output terminal (4) for connection to a satellite receiver and outputs (72) being connected to control inputs of individual switches, while the command decoding unit (7) is provided with a circuitry for a transfer of mechanical positioning equipment standard control commands to pulses controlling individual switches (2).
