Abstract
A variable vacuum capacitor includes two pairs of electrodes ganged together in series such that no moving parts are required to connect electrically to any static pans. Two sets, or gangs, of movable electrodes are connected mechanically and electrically together such that they move together and such that they require no electrical connection to any other part of the device. The ganged arrangement means that the device can be constructed with a smaller diameter, but without significantly increasing the overall length of the device.
