Abstract: A television receiver of the type capable of displaying standard VHF and UHF televison signals is provided with a single coaxial antenna input terminal. A passive input circuit within the receiver includes two filter sections for separating the VHF and UHF components of a combined VHF-UHF signal applied to the input terminal for application to separate VHF and UHF tuning sections of the receiver. The first filter section, which is located within the UHF tuning section, includes a UHF tuning line for coupling the UHF component to the UHF tuning section. The second filter section, which is located in the VHF filter section, and incorporates elements of the first filter section, enhances the response of the receiver over transition frequencies between the VHF and UHF bands.

Abstract: A combination VHF, UHF and superband tuner, the superband and UHF tuners cooperating with the Channel 1 section of the VHF tuner, is provided with a connection network including voltage sensitive switching devices, such as voltage sensitive diodes, so that selectively energizing a particular desired tuner by applying a supply voltage thereto will automatically effect the appropriate interconnections between the tuning units to render the selected tuner operatively effective and the non-selected tuners non-interfering therewith.
