PROBLEM TO BE SOLVED: To provide a radio repeating installation that can sufficiently ensure attenuation between a transmitter and a receiver with respect to a sneaked path wave, fully reducing the effect of the sneaked path wave. SOLUTION: An adaptive array antenna is adopted for a reception antenna 13 or a transmission antenna 24. Then in a training operation mode, a sneaked path direction of a sneaked path arrival direction is detected, on the basis of a reference signal generated by a reference signal generating section 30. In normal operation mode, the directivity of the reception antenna 13 or the transmission antenna 24 is adjusted, to decrease the directivity in the sneaked path direction or the sneaked path wave arrival direction. |
