Overview

The CPI Antenna Technologies’ 7.3 meter antenna delivers exceptional performance for transmit/receive and receive only applications for L through DBS Band frequencies. This antenna offers a reflector design that incorporates precision-formed panels, contoured radials and a machined 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. The reflector is supported by a galvanized 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 (F3, E3) and Eutelsat (L, S1) requirements. All configurations meet our own type-approved quality assurance and performance guarantee.
