Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a receiving device for preventing saturation in a booster circuit and a front end and evading the occurrence of a reception fault, and also to provide a booster apparatus. SOLUTION: The frequency information of a broadcasting wave acquired by channel scanning is compared with prescribed frequency information. When a superimposed band does not exist, a filter for blocking the band without the existence of the broadcasting wave is inserted, so as to prevent deterioration in reception performance owing to a useless wave.
