ThinAir Falcon-Ka2517

Uniquely Enabling General Business Aviation and Commercial Air Transport Connectivity 3x-8x More Throughput at 2x-10x the Efficiency, 1/2 the Size and 1/3 the Aerodynamic Drag

ThinKom’s agile, ultra-low-profile, high-efficiency ThinAir® Falcon-Ka2517 antenna provides high throughput (up to 50 Mbps Downlink and 15 Mbps Uplink) and with maximally efficient use of transponder bandwidth (1.5-3 bits/Hz). Our very low profile antenna design enables a similarly low profile conformal radome which reduces fuel costs related to drag by up to 80% and provides flexibility for installation on Business, Regional, Single-aisle and Twin-aisle aircraft.

The superior high skew angle and low latitude performance also improves fleet flexibility in equatorial regions.

ThinAir® Falcon-Ka2517 revolutionizes next generation “big pipe” demand for broadband in-flight connectivity using Ka-band High Throughput Satellites.
