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.
FEATURES:
• Bolt-together, all-aluminum reflector
with self-aligning, fully interchangeable
components
• Designed for 1.5 to 31 GHz operation,
meeting FCC 25.209 and ITU-RS-580
regulations
• Galvanized steel elevation-over-azimuth
pedestal with jackscrews
• Survives 125 mph winds in any position
OPTIONS:
• L, S, C, X, Ku and DBS Ka-Band feeds
• C/Ku receive only feed systems
• Specialized feed systems
(e.g., extended, multi-band)
• Antenna control system with tracking
• Reflector and feed deicing systems
• Environmental hub configurations
• Integrated transmit cross axis kits
• Integrated LNA or LNB systems
• HPAs, converters and M&C systems
• Load frame mounts
• Packing for sea and air transport
• Turnkey installation and testing
UPGRADES:
• Extended azimuth travel
• Low operating temperatures
• High power configurations
BENEFITS:
• High antenna efficiency
• Excellent rejection of noise and
microwave interference
APPLICATIONS:
• Communications, Data Transfer, Broadcast
