CPI SAT 11.1M Cassegrain Motorized Satcom Antenna System
Fully interchangeable reflector components with aluminum reflector panels and galvanized steel backup structure. Designed for 1.5 to 18 GHz operation, meeting FCC and ITU-RS- 580 requirements
11.1 Meter TX/RX Antenna
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 11.1-meter antenna delivers exceptional performance for transmit/ receive and receive only applications in L through DBS- band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, truss radials and hub assembly.
RF System
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 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.
Exceptional Performance
The electrical performance is compliant with FCC and ITU-RS-580 sidelobe specifications and Intelsat (B, C) and Eutelsat requirements.
