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

ThinKom’s agile, ThinAir ® Falcon-Ka2517 antenna provides high throughput (up to 400 Mbps Downlink and 100 Mbps Uplink) and with maximally efficient use of transponder bandwidth (1.5-3 bits/Hz). Our ultra low profile antenna design enables a similarly low profile conformal radome which virtually eliminates fuel costs related to drag 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, or military WGS services.
