ThinAir Eagle-Ka1000

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 20 Mbps Downlink at 11.5 dB/K G/T and 8 Mbps Uplink at 44dBW EIRP) and highly efficient use of transponder bandwidth (1-2 bits/Hz).

Our small swept volume, enables a similarly small form-factor fuselage mount radome which reduces fuel costs and provides flexibility for installation to a broad range of General Business Aviation and Government users looking for an effective alterna- tive to a 30cm parabolic tail pod installation.

The superior high latitude and skew angle performance improves flexibility of fleet operations throughout the world. The ThinAir® Eagle-Ka1000 supports dual-use and global applications including WGS and all Commercial Ka-band services.
