Abstract

PURPOSE:To perform remote control of tuning of the antenna circuit with the receiver, by feeding the control signal to the antenna circuit having the antenna element of bent transmission conductor line, variable reactance circuit and frequency discriminating circuit via the coaxial cable. CONSTITUTION:The antenna circuit 1 consists of the antenna elements 2a, 2b of bent transmission conductor line, variable reactance circuits 4a, 4b having varactor diodes D5a, D5b, and frequency discrimination circuit 16 with PLL circuit and frequency division circuit. The reception signal from the circuit 1 is fed to the receiver 17 via the coaxial cable 31. The control signal from the frequency divider of the synthesizer 18 in the receiver 17 is fed to the frequency divider 11 of the circuit 16 via the LPF25, cable 31 and LPF10. The signal frequency-divided at the frequency divider 11 is fed to the PLL circuit to pick up the DC voltage corresponding to the frequency of the control signal from the output side of LPF13 and fed to D5a, D5b. Thus, the tuning of the antenna circuit can be remote-controlled from the receiver 17.
