PURPOSE:To make the fine adjustment of the polarization switch of a CS antenna to be accurate and easy. CONSTITUTION:In the CS receiver consisting of the CS antenna 1 having the polarization switch 3, etc., and a tuner 5 selecting the station of a desired channel from CS-1F from the antenna and outputting a signal such as a video, a sound, etc., the signal level of a reception channel is detected by way of BPF 7. Then, the interference signal of a cross polarization component is detected by way of a comb line filter 9 and a control part 13 controls the polarization switch 3 so as to make the level difference of the detected signal to be maximum.
