The respective transmission lines is provided with a first to a third power supply filters 45c, 45f, and 45e, and a first to a third filter means 41, 44, and 43. Output terminals of the second transmission line 30f and the third transmission line 30e are connected. A fourth filter means 42, which passes the BS/CS signal and the satellite digital audio broadcast signal in the transmission line led out from the connecting point. The first transmission line 30c and the output terminal passed through the fourth filter means 42 are connected, and are connected to the output terminal via a fourth power supply filter 45d.
