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.
