reception unit for polarized microwaves primarily - satellite and receiving with such unit.

摘要

A receiving head end comprising only a single movable component, a front depolarizer (POM), for selecting conjugate polarized microwaves. The addition of a fixed depolarizer (POF) provides two aerial versions, one for the circular type of polarization and the other for the rectilinear type of polarization. The whole is fitted together for forming an aerial for the "public at large", simple to operate and whose shadow cast on the parabolic reflector is minimal.
