Summary:PROBLEM TO BE SOLVED: To prevent reduction in the reception sensitivity even when a reflecting wave is in existence. SOLUTION: A plane antenna 1 is controlled to be driven so as to be in matching with a direction of a broadcast satellite and its elevating angle is controlled electronically. Only a direct wave of a radio wave from the broadcast satellite is made incident to the plane antenna 1 and the reflected wave is shielded by a metallic shield plate 2 provided to a radome 3 and not made incident in the plane antenna 1. Thus, interference by a reflecting wave is prevented.
