The Collins Aerospace HGA-2100B SATCOM High Gain Antenna complies with ARINC 781 and offers a low profile, electronic steering and phased array. It also complies with Inmarsat requirements for high-gain service and optimizes SwiftBroadband operations. The antenna contains an integrated beam-steering unit and receives command information directly from the Satellite Data Unit.

Ideal for installations that require a compact system, the HGA-2100B provides a cost-effective solution with a very low drag-to-weight ratio. It is approved for safety service operations.
