PROBLEM TO BE SOLVED: To provide a mobile radio station which can automatically avoid an antenna azimuth applying radio wave interference to adjacent fixed radio stations. SOLUTION: The mobile radio station 10 holds a position of a fixed radio station 20 in all expected moving areas of the mobile radio station 10 and information about an azimuth setting prohibition area where the fixed station 20 undergoes the radiowave interference for each position in the form of a database, and transmits a control signal to an antenna horizontal drive motor 13 from a CPU 17 to automatically avoid the azimuth setting prohibition area of an antenna 11 on the basis of position information 41 and antenna installation azimuth information 42 from a GPS sensor 14 and a terrestrial magnetism sensor 15 provided in the mobile station 10.
