PURPOSE:To enable a selective reception of a horizontal polarization signal or a vertical polarization signal by receiving a signal from a broadcasting satellite in the operating state of a converter and giving it to a receiver through a switching device. CONSTITUTION:When the vertical switch 20 of one side of a receiver 18 is set as on and the horizontal switch 21 of the other side of the receiver 18 is set as on, electric power for operating the converter that is outputted from the one side of the receiver 18 is supplied to a converter 4 through a switching device 10 and the electric power for operating the converter that is outputted from the other side of the receiver 18 is supplied to a converter 5 through the switching device 10. Thereby, the converters 4 and 5 receive the vertical polarization signal and the horizontal polarization signal from the broadcasting satellite through an antenna A. Therefore, each receiver 18 is able to receive the vertical polarization signal and the horizontal polarization signal separately.
