PROBLEM TO BE SOLVED: To provide a radio equipment that detects a fault in a transmission system even when a transmission reception common use antenna and a reception exclusive antenna are mounted at an optional position such as a place at which an antenna characteristic is not deteriorated due to surrounding buildings or the like. SOLUTION: The radio equipment is provided with a reception antenna 4 that receives part of a transmission signal outputted from a transmission antenna and connects to a detection circuit and detects a fault of a transmission signal outputted from the transmission antenna 1 based on an output level of the detection circuit. A level adjustment means 20 is placed to a pre-stage of the detection circuit so as to detect the fault of the transmission signal outputted from the transmission antenna 1 independently of an installation distance between the transmission antenna 1 and the reception antenna 4. |
