CPI SAT 13.2M Ka-Band Broadband Gateway Antenna System
Precision Ka-band rated surface reflector with counterweights, Transmit signal block downconverters to allow spectrum monitoring at L-band in the control building.
13.2 Meter Ka-Band Antenna
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 13.2M Ka-Band Satellite Earth Station antenna is ideal for IOT, TT&C, DTH, and High Power Uplink applications. Large diameter Ka-band antennas require unique design criteria which GD Satcom has successfully demonstrated with 13.2 meter system. 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. Our proven 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.
