Abstract
An apparatus for reducing earth station interference in a receiver antenna from non-GSO and terrestrial sources is disclosed. The apparatus comprises an absorber coupled to a receiver antenna feed assembly disposed between the non-GSO or terrestrial source and the feed assembly. Embodiments are disclosed in which the absorber is strategically placed where it minimally affects the receiver antenna mainlobe performance, while reducing interference from non-GSO and terrestrial sources.
