AvL’s 3.8m Rugged Vehicle/Trailer-Mount WGS-Ready Antenna is a quick-deploy antenna with an innovative feed that enables operation in simultaneous dual X- and Ka-bands. The antenna was designed for heavy duty military applications and mounting onto a MILSATCOM trailer. The antenna is high-wind tolerant with wind compensation tracking, and the 3.8m carbon fiber reflector can be segmented into three pieces for transport on a truck or trailer.

The AvL antenna control system is embedded on the antenna with a built-in compass, GPS and tilt compensation. The auto-acquisition controller is ethernet based, modem agnostic, OpenAMIP compliant, up-to-date with the latest cybersecurity, and operates with a web-based user interface that can be used on a phone, laptop or PC. The controller includes a satellite profile management system, a built-in AvL carrier/beacon receiver with an optional rack-mount interface panel or outdoor rated power supply and offers intelligent tracking and multi-orbit capabilities. Power requirements vary by antenna.
