Abstract
A satellite signal splitter is proposed which can transmit a received signal of a desired polarized wave with one cable to each terminal side when transmitting to plural terminal sides the received signals from a satellite receiving antenna which emits the received signals of a vertically polarized wave and a horizontally polarized wave. The vertically and horizontally polarized-wave received signals transmitted to input terminals 22V and 22H are split into four by splitting circuits 26V and 26H, respectively. The four split signals are transmitted to switching circuits 28a to 28d. In the switching circuits 28a to 28d, in accordance with a voltage level (11V or 15V) of a polarized-wave switching signal transmitted from terminal units connected to output terminals 24a to 24d, either the vertically or horizontally polarized-wave signal is selected and emitted from the output terminals 24a to 24d. Also, the polarized-wave switching signal (11V or 15V) is transmitted via a voltage synthesizing portion 30, choke coils LV, LH and the like from the input terminals 22V and 22H to a corresponding receiving portion of a receiving antenna.
