Self-aligning wave guide interface

摘要

A microwave guide interface extends between a rear surface of a microwave antenna reflector and a facing surface of a base plate. An interconnect member having a ball surface extends rearwardly from the rear of the reflector. A second interconnect member having a ball-receiving socket extends forwardly from a facing surface of the base plate. A spring clamp is attached to a periphery of the base plate and includes a yoke coacting with a strike hook on a circular rib or on separate lugs extending from the rear of the reflector for cinching up the socket into abutting contact with the mating ball surface. A peripheral O-ring extends between peripheral surfaces of the members allows tilting of the assembly such that assembly and alignment can be made over a fairly wide range of angular tolerances of the base plate and reflector. This is especially desirous since the base plate and electronic packages thereon are relatively heavy and unwieldy and normally must be attached, or reattached if a polarization change is needed, to a reflector adjustably fixed high on a tower or pole.
