摘要： A digital tuner unit receiving a digital signal in a reception channel having a predetermined bandwidth is connected at a subsequent stage of an antenna device containing radiation conductors and varactor diodes. A digital reception signal output from the digital tuner unit is input to a demodulation circuit and subjected to demodulation. An SP level detection unit of the demodulation circuit detects levels of a plurality of spread pilot signals in the bandwidth of the reception channel, and obtains a correction amount for a tuning voltage so that a level difference can be reduced to a predetermined value or less using the correction amount. The SP level detection unit reports the correction amount to an antenna tuning control unit so that the tuning voltage to be supplied to the antenna device can be corrected using the correction amount.
