Overview
Large diameter Ka-band antennas require unique design criteria which General Dynamcis SATCOM Technologies has successfully demonstrated with both the 9.2 and 13.2 meter products. Items such as reflector surface accuracy, antenna/ feed design, structural antenna stiffness and integrity, thermal effects, anti-icing, HPA phase combining, monopulse tracking, installation and alignments and hub integration all require special engineering expertise at Ka-band. SATCOM Technologies has proven our expertise in the above areas and has earned the position as a preferred antenna system provider and integrator to a number of major satellite broadcasting companies by providing in excess of fifty systems of this type over the past five years alone.
