ABSTRACT:
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.
