Abstract
A vehicle radio receiver apparatus constitutes an antenna device including an antenna element and also a radio receiver integral with the antenna device so as to receive a signal from the antenna element. The radio receiver includes a tuner circuit directly connected to the antenna element, a high-frequency amplifier circuit for amplifying the reception signal tuned into by the tuner circuit, and an audio signal converter for detecting and low-frequency amplifying a high-frequency amplified signal and for producing an audio signal. A tuning control signal and a volume control signal are respectively supplied from a control unit to the tuning circuit and the audio signal converter circuit of the radio receiver. This control unit is arranged separately from the radio receiver and receives volume control and tuning control operating signals from an operating section which has a tuning control knob, a volume control knob and the like. The operating signals are transmitted to the antenna element and to the radio receiver through the transmission line.
