Viasat 7.3m Ka-band Broadband Gateway Earth Station Antenna

The Viasat 7.3m Earth Station Antenna is ideally suited to high-performance Ka-band geostationary applications. The shaped Cassegrain reflector provides superior gain and sidelobe performance at Ka-band frequencies.

High precision stretch formed panels are supported by strong radial trusses attached to a large central hub. Spars support a high-precision machined subreflector.

Thermal effects at Ka-band are minimized by aluminum reflector materials coated with solar diffusive white paint. The reflector back structure and subreflector spars are designed to stringent Ka-band rigidity requirements under wind and gravity loads.

The oversized hub provides a protective enclosure for sensitive electronics with ample space for equipment such as HPAs. The large extended work platform provides easy access to the hub. Transmit path losses are improved by storing the HPAs in the hub.

The precision steel mount delivers extremely accurate Ka- band pointing even under adverse wind conditions. The pedestal design features a precision azimuth bearing and very low backlash for high performance.

ViaSat’s Antenna Control Units are ideally suited for controlling the Ka-band antenna, offering full DC servo performance and adaptive step tracking or monopulse autotrack options depending on the desired tracking accuracy.
