Abstract
A satellite signal receiving apparatus including a channel selector, an outdoor unit and a single transmission line connecting therebetween. The satellite signal receiving apparatus has such a simple structure that the installation work thereof is simple. In the satellite signal receiving apparatus, by superposing a pulse train over a source voltage supplied from the channel selector to the outdoor unit, the type of the polarized radiation signal to be output from the outdoor unit as transmission signal is switched. Since no change of the source voltage is required for switching the type of the polarized radiation signal, appropriate source voltage can be supplied to the outdoor unit. Furthermore, since no action against the heat released by a constant-voltage circuit is necessary, the type of the polarized radiation signal can be switched easily. Even if the source voltage varies with the length of the transmission line, the type of the polarized radiation signal can be switched effectively and stably.
