Abstract

PURPOSE:To secure the optional mixing of the desired signals through selection of the additional circuit, by coupling plural number of antenna signals via the basic circuit and then securing alteration of the mixture contents of the signals via the interruption of the specified antenna signal from the additional circuit. CONSTITUTION:The mutual connection is given between connection bars A and B at connection parts 1-3 of basic circuit plate BU, and thus the mixture is possible for the TV signals of both UHF and VHF. Then the UHF signal is applied to output terminal OUT via impedance converter BAL and HPF; and the VHF input is applied to terminal OUT via LPF each. At the same time, band blocking filter BOF which blocks the signal of the specified channel among the signal sent from UHF input terminal U-ANT2 is provided to additional circuit CU, along with BPF which gives transmission to the signals of the channels other than the specified one. And connection bars A' and B' at connection part 1 are connected to bars A and B of plate BU in order to secure the interruption for the signal of the specific channel. Thus the optional mixing is secured for the desired signals through selection of additional circuit CU.
