Abstract

PURPOSE:To enable the channel selection of a TV receiver very easily, by automatically performing the selective connection to antenna used to each reception channel at the same time with channel selection. CONSTITUTION:The electronic tuner 100 changes the DC voltage fed and selects the frequency band and reception channel, and in electronic switches 1,2..., one of them is exclusively triggered and operated with channel selection. When a specific circuit is operated among the switches 1,2...N1,N2, the antenna terminal 101 of the tuner 100 is selected from the main antenna 400 to the sub-antenna 500 with the DC voltage produced from this circuit. Thus, the channel selection of the TV receiver can be made very easily.
