An antenna tuning apparatus for VHF/UHFantenna comprises an automatic gain control(AGC) arrangement, including an amplifier,the gain of which is controlled by the AGCarrangement, and a plurality of impedancematching networks which are coupled betweenan antenna input of the tuning apparatus andthe AGC-controlled amplifier. A remotecontroller is provided to select both channelsof a television apparatus, for which the tuningapparatus provides VHF/UHF signals, and propermatching networks suitable for respective onesof selected channels simultaneously. Each oneof the plurality of matching networks exlusivelyprovides the AGC arrangement with a respectivegroup of RF signals which includes a pluralityof receivable broadcast channels. The gain of theamplifier is controlled in response to the level ofthe group of RF signals.
