ThinAir Eagle-Ka2000

Delivering General Business Aviation, Transport and Government Users Broadband Connectivity in a Low-Profile, Small Form-Factor Fuselage Mount Antenna

ThinKom’s agile, low-profile, high-efficiency antenna provides high throughput (up to 30 Mbps Downlink at 15 dB/K G/T and 12 Mbps Uplink at 48 dBW EIRP) with efficient use of transponder bandwidth (1.5-3 bits/Hz). Our small swept volume, enables a similarly small form-factor fuselage mount radome which reduces fuel costs and provides flexibility for installation on a broad range of regional jet, single-aisle and twin-aisle aircraft.

The superior high latitude and low skew angle performance improves flexibility of fleet operations throughout the world, including equatorial regions.

ThinAir® Eagle-Ka2000 supports dual-use and global applications including WGS and all Commercial Ka-band services.
