Overview

The CPI Satcom & Antenna Technologies Inc.
(CPI SAT) 4.8 meter antenna delivers exceptional
performance for transmit/receive and receive onlyapplications for C through Ku-Band frequencies.
This antenna offers a deep dish reflector thatincorporates precision-formed panels, contoured
radials and hub assembly. It features an innovative
feed and subreflector design which results inhigh gain, low noise temperature, high antenna
efficiency and excellent rejection of noise andmicrowave interference.
The aluminum reflector is supported by agalvanized pedestal that provides the required
stiffness for pointing and tracking accuracy.
The pedestals are designed for full orbitalarc coverage and are readily adaptable toground or rooftop installations. The electricalperformance is compliant with ITU and FCC
sidelobe specifications. Type approved
configurations are available for Intelsat (F1, E2),
Eutelsat (L), Asiasat, Hispasat, EuropeStar orSingapore Telecom. All configurations meet
CPI Satcom & Antenna Technologies Inc.
(CPI SAT) own type-approved quality assurance
and performance guarantee.

OPTIONS:• C, X, Ku, DBS and Ka-Band feed configurations• C/Ku receive-only feed systems• Specialized feed systems(e.g., extended, multi-band)• Improved feed cross-pol performance• Fixed or motorizable pedestal mounts• 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• Non-penetrating and load frame mounts• Packing for sea and air transport• Turnkey installation and testing
UPGRADES:• X-Band low PIM reflector/feed
configurations• Extended azimuth travel• High wind configuration• Low operating temperatures• High power configurations• Ka-Band (see separate datasheet)
BENEFITS:• High antenna efficiency• Excellent rejection of noise andmicrowave interference
APPLICATIONS:• Communications, Data Transfer, Broadcast
