PURPOSE:To enable stable communication by detecting the fault of an antenna in use during an operation (during the communication) in real time in a diversity radio equipment. CONSTITUTION:The reception electric field output (values) of receivers 11 and 12 constituting the diversity radio equipment are continuously monitored by the unit of a fixed time and peak values in the fixed time are detected by peak detectors 41 and 42. Then, The peak values corresponding to the receivers 11 and 12 are compared by a compartor 2 and when a difference becomes equal to or more than a fixed value, the antenna connected to the receiver for which the low value is deteced is judged as the fault. |
