CPI SAT 9.0M Cassegrain Satellite Earth Station Antenna
L, S, C, X, Ku, DBS and Ka-band feed configurations, C/Ku receive-only feed systems
9.0 Meter Gateway Earth Station
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 9.0-meter antenna delivers exceptional performance for transmit/ receive and receive only applications for L through Ka-band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, truss radials and hub assembly using matched tooling for interchangeable components. It features an innovative Cassegrain feed and subreflector design which results in high gain, low noise temperature, high antenna efficiency and excellent rejection of noise and microwave interference.
Integration
A large center hub provides spacious accommodation for equipment mounting. The reflector is supported by a galvanized elevation over azimuth kingpost pedestal that provides the required stiffness for pointing and tracking accuracy. The pedestals are designed for full orbital arc coverage and are readily adaptable to ground or rooftop installations.
RF
The electrical performance is compliant with FCC 25.209 regulations, ITU-RS-580 sidelobe specifications and Intelsat (F3) and Eutelsat requirements. All-aluminum reflector with fully interchangeable components , Designed for 1.5 to 18 GHz operation, meeting FCC and ITU-RS-580 requirements , Galvanized steel elevation over azimuth pedestal with jackscrews , Survives 125 mph winds in any position
