AvL’s 4.6m high-gain, multi-band and multi-orbit flyaway antenna originally was designed to meet custom specifications and numerous application-specific iterations have been designed since. AvL selected the core design with key application-specific features as a standardized antenna, which is now available. The standard configuration antenna packs into 24 cases (excluding feeds) for shipping via commercial air freight and all cases meet 2-man lift requirements. The antenna can be assembled by a four-person team in less than three hours and operates in standard C-band or optional Ku-, Ka-, X-, S- or S/L-band, or C-band troposcatter. The antenna is motorized with auto-acquisition and can operate in 30 mph (48 kph) winds with gusts to 65 mph (105 kph).

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.
