About
Calian’s 4m Satcom Antenna is a compact, high-accuracy dual-reflector Cassegrain earth station system suitable for many SATCOM applications including gateways, telemetry/tracking/command (TT&C), and enterprise connectivity. Supporting C, Ka, Ku, S, and X frequency bands, the 4m system offers GEO, LEO, and MEO orbit compatibility, making it versatile for both fixed satellite service and non-geostationary constellations. The aluminum main reflector surface accuracy is below 0.008 inch RMS and the carbon fibre composite sub-reflector is below 0.002 inch RMS. The elevation-over-azimuth 2-axis pedestal features state-of-the-art cable wrap. Optional features include a de-icing system, environmentally controlled hub, and adjustable polarization. Ethernet M&C interface provides full remote monitoring and control. Operating temperature: -30 to +60 °C.
