ABSTRACT:
A tunable capacitor comprises a cylindrical stator having a pair of fixed terminals and a cylindrical rotor telescopically mounted in radial alignment with the stator for rotary positionable adjustments with respect thereto. The stator has a pair of axially spaced, arcuate electrodes connected with the terminals. The rotor has an arcuate electrode that extends axially a distance sufficient to overlap at least portions of the stator electrodes in selected rotary positions with respect thereto.
