PURPOSE:To allow a UHF/VHF uniaxial tuner to select UHF/VHF ANT signals simultaneously. CONSTITUTION:A UHF/VHF 75OMEGA uniaxial ANT signal is given to an F receptacle plug 4 and when no VTR is connected, a plate spring switch 3 is closed, F receptacle male plugs 1b, 2b are connected and the signal is inputted to a TVANT through an F receptacle plug 5. On the other hand, when a VTR video signal is monitored on a TV, the F receptacle male plugs 1b, 2b connecting to an RF converter 16 are plugged into F receptacle female terminals 11, 12 in one-touch. In this case, the F receptacle male plugs 1b, 2b are not in contact with each other by the insertion of them to the F female plugs 11, 12 of the RF converter 16 in the plate spring switch 3, the F receptacle male plug 1b and the F receptacle female plug 11 of a terminal IN, and the F receptacle male plug 2b and the F receptacle male plug 12 of a terminal OUT are respectively connected and an ANT signal is distributed to the VTR 75OMEGA uniaxial tuner and the TV ANT. |
