ABSTRACT:
A UHF tuner employing resonant cavities with tuned lines has a discrete air trimmer capacitor which includes a fixed electrode connected to the tunable line with one or more insulated turns of silver wire and a movable electrode guided into the fixed electrode to provide characteristics of lower minimum capacity, higher maximum to minimum capacity ratio, smaller physical size, higher Q and lower cost than conventional capacitor trimmers.
