Rotorcraft Report: EMS SATCOM Announces New AMT-700 Antenna

By Staff Writer | November 1, 2008


EMS SATCOM, a division of EMS Technologies, introduced its eNfusion AMT-700 high-gain antenna (HGA) at the National Business Aviation Association Annual Meeting and Convention in October. The antenna was designed with Inmarsat’s new SwiftBroadband service in mind, providing higher gain than competing antennas of similar size and weight, the company said.

Its design was based on the strong pedigree of its successful sister antenna, the AMT-50 HGA, currently flying on more than 1,400 aircraft.

John Broughton, vice president of product development said, "Our AMT-700 HGA builds on more than 15 years’ experience and millions of flight hours of the AMT-50 HGA. More important, this new antenna incorporates several new technological advances initially brought to market in our AMT-3800 phased-array product. By maximizing data throughput and system capacity, these advances are designed to get the most out of Inmarsat’s SwiftBroadband service."


Composed of two Line Replaceable Units, the AMT-700 HGA is EMS SATCOM’s next generation of high-gain antenna. Featuring lower power consumption, higher gain (>13.5dB) and a small footprint, it is specifically designed to meet or exceed the most stringent SwiftBroadband requirements. The antenna control functions have been integrated into the antenna package, offering more flexible installation. Weighing in at less than five pd, it is the lightest of EMS SATCOM’s line of eNfusion antennas.

The first variant to be available will be DC-powered, with an AC model to follow. The antenna is planned to be commercially available in May 2009.
