<p>PROBLEM TO BE SOLVED: To enhance reception and regeneration quality of multiple broadcasting waves by greatly restricting influences of a multipath reflected waves, diffracted waves, or the like. SOLUTION: A mobile mounted receiver can receive a broadcasting signal to be transmitted from a geostationary satellite 2, having a wave angle of a predetermined angle. The receiver comprises a pair of antennas 6a, 6b, having prescribed directivity, and a directivity control unit 13 for periodically rotating directivity patterns of the pair of antennas 6a, 6b, while an angle with respect to the horizontal surface substantially is made to coincide with the wave angle.</p> |
