The Strength to Perform

The General Dynamics SATCOM Technologies 6.3-meter antenna delivers exceptional performance for transmit/receive and receive-only applications for C through Ku-band frequencies. This antenna offers a deep dish reflector that incorporates precision-formed panels, contoured radials and hub assembly. It features an innovative feed and subreflector design which results in high gain, low noise temperature, high antenna efficiency and excellent rejection of noise and microwave interference.

Product Details

The aluminum 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 ITU and FCC sidelobe specifications. Type Approved configurations are available for Intelsat (F2, E2), Asiasat, Hispasat or Singapore Telecom. All configurations meet SATCOM Technologies’ own type approved quality assurance and performance guarantee.
