ター。 When connected to the UHF/VHF 75Ω mixed terminal of a television receiver, the UHF/VHF mixed signal transmitted via the coaxial cable is
UHF/VHF input to HF75Ω mixed terminal
When the 75Ω mixed plug and the UHF/VHF 75Ω mixed plug are not connected to the UHF/VHF 75Ω mixed terminal, the UHF/VHF mixed signal transmitted through the coaxial cable is converted into a UHF signal and a VHF signal.
A separation filter that separates the HF signal and a UHF signal obtained by the separation filter from 75Ω to 300Ω.
When connected to the UHF 300Ω terminal of the television receiver via the UHF parallel two-wire feeder line, and the VHF 75Ω terminal of the television receiver, the separation filter converts the impedance to Ω. A VHF75Ω plug inputs the obtained VHF signal to the VHF75Ω terminal, and when the VHF75Ω plug is not connected to the VHF75Ω terminal, the VHF signal obtained by the separation filter is input to the VHF75Ω terminal.
In addition to converting the impedance from to 300Ω,
VH input to the VHF 300Ω terminal of a television receiver via a VHF parallel two-wire feeder line
F conversion transformer, the UHF/VHF75Ω mixed plug, the separation filter, the UHF conversion transformer, the VHF75Ω plug, and the VH
An integrated UHF/VHF adapter characterized by consisting of a single housing member that houses an F conversion transformer.
