GDSatcom 9.2m Ka-band Extended Azimuth Earth Station Antenna

Large diameter Ka-band antennas require unique design criteria which General Dynamcis SATCOM Technologies (GDSatcom) has successfully demonstrated with both the 9.2 and 13.2m products. Items such as reflector surface accuracy, antenna/ feed design, structural antenna stiffness and integrity, thermal effects, anti-icing, HPA phase combining, mono-pulse tracking, installation and alignments and hub integration all require special engineering expertise at Ka-band.

SATCOM Technologies has proven their expertise in the above areas and has earned the position as a preferred antenna system provider to a number of major satellite broadcasting companies like Hellas-Sat, Inmarsat and Intelsat by providing in excess of fifty systems of this type over the past five years alone.
