CPI SAT 16.4 Meter Intelsat Gateway Antenna System
Galvanized steel elevation over azimuth pedestal with jackscrews, Survives 125 mph winds in any position, L, S, C, X and Ku-band feed configurations
16.4 Meter Intelsat Standard "A" Earth Station
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 16.4-meter antenna delivers exceptional performance for transmit/ receive and receive only applications in L through Ku-band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, truss radials and hub assembly. 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. A large center hub provides spacious accommodation for equipment mounting.
Rugged
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. The electrical performance is compliant with FCC and ITU-RS-580 sidelobe specifications and Intelsat (A) and Eutelsat requirements.
