Abstract

PURPOSE:To simplify the connection between the power feed line and television and to make low in the loss, by making bundle the antenna input terminals in common use and separate for VHF and UHF. CONSTITUTION:When the VHF.CHF signal is mixed at the antenna and input from the coaxial cable, the coaxial cable 6 is connected to the input terminal 3. Thus, the VHF signal is branched with UHF signal at the branch unit 11 and output from the terminal 9, and UHF signal is fed to the UHF exclusive use terminal 4 from the balance terminal 5 for jumper via the branch unit and balun 12. Further, when VHF, UHF are connected with separate feeding lines, the VHF signal is connected to the terminal 3 and the UHF signal is to the terminal 4.
