The CPI SAT (formerly GD Satcom Technologies & Prodelin) 8.1M KPC & KPK antenna delivers exceptional performance for transmit/ receive and receive-only applications for L to Ku-band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, truss radials and hub assembly.
Exceptional Performance
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. The aluminum 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 Specifications
The electrical performance is compliant with ITU and FCC sidelobe specifications and Intelsat (F3) and Eutelsat requirements.
