GD Satcom Model 3.8M Dual Offset Antenna

The General Dynamics SATCOM Technologies 3.8-meter Antenna delivers exceptional performance for transmit/receive and receive only applications in L through Ka-Band frequencies. This antenna offers a dual offset reflector design that incorporates precision-formed panels, contoured radials and a machined hub assembly. The state-of-the-art design provides exceptional performance for low cross-polarization levels and excellent sidelobe patterns. The rugged feed boom can support up to 300 lbs. (136 kg) of integration equipment. The reflector is supported by a galvanized steel fixed or motorizable 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 using concrete foundations, load-frames or non-penetrating mounts. The electrical performance is compliant with FCC 25.209 regulations and ITU-RS-580 sidelobe specifications. Type Approved configurations are available for Intelsat (F1, E2), Eutelsat (L, M), Asiasat, Europe Star and Singapore Telecom.

The Strength to Perform
