High power positional fixture for a multi-polarized antenna

摘要

A compact fixturing means is disclosed that delivers two or more phase tracked channels of high power (e.g., 1000 Watts) to an antenna that can produce a multiplicity of polarization depending on the phase relationship of the delivered signals. Coaxial cables are used as a service loop to provide two or more channels of phase tracking and high power signals to the multi-polarized antenna. A flat spiral spring is configured within the fixture to the guide two (or more) coaxial cables along a spiral loop to allow approximately equal tension on the cables as the fixture is rotated. The flat spiral spring is operatively coupled to a rotation plate and progresses form an inner radius proximate the fixture input to an outer radius proximate the fixture output.
