PURPOSE:To detect a signal in a position separated from an antenna without lowering of S/N and sensitivity, by providing a receiver, which receives the high frequency signal from the antenna, near the antenna and by driving a light emitting element by the signal from this receiver and by transmitting the optical signal through an optical fiber. CONSTITUTION:A receiver which receives the high frequency signal from an antenna to lead out a frequency modulated signal is provided near the antenna. A light emitting element 68 is driven by the output of this receiver to generate an optical signal. An optical fiber 54 is used to transfer this optical signal to a receiving device in a separate position. |
