A power coupler that is held in place at two different points along its length to substantially eliminate any movement thereof due to vibration of the environment. One of these holding means comprises a piece of dielectric which snugly encloses the coupler to prevent side-to-side movement while still allowing a vertical adjustment of the coupler element through the holding means. A constant impedance equal to that of an electrically connected circuit is maintained along a portion of the coupler by varying passageway opening sizes. The electrical connection to the circuit, which has a threaded terminal comprising a part of the adjustment means and the other holding means eliminates connector insertion loss and signal reflections inherent in prior art signal interfaces between the coupler and an electrical signal receiving circuit.

Anti-microphonic power coupling apparatus

A concept previously used for providing anti-rotational locking of complementary threaded devices is utilized in a RF tuning cavity to minimize anti-microphonic disturbances of the prior art caused by inconsistent ohmic contact between the prior art adjustable length threaded portions. The use of a resilient locking strip embedded longitudinally into the threads of an adjustable resonator provides substantially constant electrical or ohmic contact between the two threaded portions so as to maintain a standing wave in the tuning element. The longitudinal design of the locking strip is such as to prevent or minimize movement of the extremity of the threaded resonator which movement can also effect the resonant frequency.
