Abstract: A self-pointing antenna has a reflector, a feed or a sub-reflector and a plurality of support struts coupled between the reflector and the boom arm and supporting the feed or sub-reflector. At least one actuator is operatively coupled with the support struts for adjusting the position of the feed or sub-reflector relative to the reflector so as to selectively adjust either/or both of the beam elevation and azimuth of a main beam axis of the antenna.

Abstract: A microwave antenna has an elongated tubular radome made of a rigid nonconductive material, and an elongated unitary core made of a rigid dielectric material and telescoped within the radome in supporting engagement with the inner surface of said radome. A pair of conductive antenna elements are affixed to the surface of the core and extend along the length thereof. A microwave transmission line is connected to the antenna elements for transmitting electromagnetic energy to and from the elements.

Abstract: An improved anti-icing and de-icing system is provided for reflector-type microwave antennas having a paraboloidal reflector and an associated feed horn for launching microwave signals onto the reflector and receiving microwave signals from the reflector. The improved system comprises a non-conductive, insulated enclosure forming an enclosed cavity adjacent the rear side of the reflector, and a radiant heating system disposed within the enclosure for heating the rear side of the reflector with radiant energy, whereby the air in said cavity is in turn heated by heat transferred to said air from the rear side of the reflector. The radiant heating system comprises at least one infra-red heating source, and is supplemented by a highly reflective mirror coating disposed on the inside surface of the insulated enclosure behind the heating source to direct the radiant energy emanating from the back of the heating source of all regions of the reflector.
