    an antenna switching device for selecting one of reception signals received by the plurality of antennas, and supplying the selected reception signal to a signal processor arranged subsequent to the antenna switching device;

    a detector for detecting the level of a reception signal from each antenna; and

    a controller for controlling the antenna switching device for selecting a reception signal having a lower level than a maximum input level of the signal processor, in accordance with detection result from the detector,wherein the controller operates to control the antenna switching device, in a manner such that once the level of a reception signal supplied to the signal processor becomes lower than a predetermined level, an antenna having a higher antenna gain than that of an antenna being selected is selected,wherein the controller has a judger for judging a reception state of each antenna; and

    when there are a plurality of antennas capable of receiving signals without any troubles, the antenna switching device is controlled so as to select a reception signal from an antenna having a low antenna gain.
