AvL’s 1.8m vehicle-mount / driveaway antennas are available in Mobile VSAT and ruggedized configurations. AvL’s 1.8m Mobile VSAT antennas operate in Ku- and C-bands, and the ruggedized antennas also operate in Ka-band for commercial, SNG and military applications. The antennas feature a vehicle-mount pallet, and the Mobile VSAT model has an engineered composite reflector whereas the ruggedized antennas features a carbon fiber reflector with surface treatment for Ka-band.

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.
