Abstract

PURPOSE: To make excellent the reception, by converting the received UHF signal into the signal having the frequency not giving effect to the signal in VHF band, changing it into UHF signal through the use of a converter, and mixing it with the VHF signal fed directly.
CONSTITUTION: The reception signal from the antennas 1 and 2 in UHF and VHF is fed to the main line branch amplifier 5 via the head amplifier 3, and this output is fed to the TV receiver 8 via the converter built-in branch unit 7. In this circuit, the branch unit 7 is constituted as follows: Between the branch unit 13 and V/U converter 17 provided between the input and output terminals 11 and 12, the level control 14 and the VHF broad band amplifier 15 are provided. After branching the specific signal at the branch unit 16 with level adjustment, conversion is made to a given UHF signal at the converter 17. After that, this signal is mixed with VHF signal not branched at the mixer 18 and it is delivered to the receiver 8 via the branch terminals 20∼23.
