CPI SAT 9.2M Ka-Band Broadband Gateway Satellite Earth Station Antenna
Ka-Band Transmit & Receive, Increased reflector surface tolerances
9.2 Meter Ka-Band Gateways
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 9.2M Ka-Band antenna delivers extraordinary performance for broadband hub & Ka-Band Satcom applications. Large diameter Ka-band antennas require unique design criteria which CPI has successfully demonstrated with both the 9.2 and 13.2 meter products.
Reflector Tolerance
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.
Innovative Design
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.
