PROBLEM TO BE SOLVED: To continue stable material transmission by receiving a transmission wave of a transmission point by means of two antennas. ! SOLUTION: A receiver includes: a rotary receive antenna part for tracking and receiving a radio wave of a material transmitted from a mobile transmission body; a first receiving part for converting the radio wave received by the rotary receive antenna part into a signal of a predetermined frequency band; a second rotary receive antenna part which is rotated on the basis of reception direction information of the rotary receive antenna part and receives the radio wave of the material; a second receiving part for converting the radio wave received by the second rotary receive antenna part into a signal of a predetermined frequency band; a reception video switching part which selectively outputs any one of the signals outputted from the first receiving part and the second receiving part; and a control part that controls switching of the reception video switching p |
