Abstract

System reflecting to the base of a satellite communications antennae providing selection of electromagnetic radiation from or to a variable position element, consists of a primary and secondary cassegrain reflector adjustable in position and azimuth together with four mirrors reflecting to the secondary mirror and a horn containing the radiating or reflecting element situated at the antennae system base. The entire reflecting system is contained in an electrostatic sheath built into which is the system rotation point. The reflector arrangement prevent cross polarisation and noise effects.
