PURPOSE:To provide a radio repeater which can stably repeat radio waves with instable received field intensity. CONSTITUTION:While an arrival of radio waves to request radio repetition is waited, a control part 5 inputs a judged output of a first received field intensity judge circuit 8 by using a judge switching circuit 10, when the received field intensity is higher than a first level, the repetition is started, the judged output of a second received field intensity judge circuit 9 is switched and inputted, the received field intensity is checked at a second level, round-off processing is performed to the received input lower than the second level, and received contents are not transmitted. The second level is lower than the first level. The radio waves lower than the first level under waiting is not repeated. |
