The GATR inflatable satellite antenna is a 1.8 or 2.4 meter diameter satellite terminal that can be transported in as few as two airline checkable case. It is used for first-in and back-up communications (including Internet access, Voice over IP, email, and video teleconferencing), broadcast television, and other high-bandwidth communications in remote environments.
The GATR antenna uses a flexible parabolic reflector mounted at the ball’s equator. The whole ball is then cabled to the ground and easily pointed using pulleys on ground mounting plates. The ball, or radome, supports the dish, protects it from wind, and keeps it pointed toward the satellite.
The main advantage of the GATR is portability; when the ball is deflated, it rolls up (with the dish inside) like a sleeping bag and weighs 18 lbs., compared to other high-bandwidth dishes that weigh hundreds of pounds and require 4 to 10 transit cases to move.
The antenna bag, blower, hoses and plates all fit in one airline checkable case. An additional case is typically provided for electronics (a modem, spectrum analyzer, RF cables, computer, power inverter, etc.), resulting in a complete, high-bandwidth satellite communications (SATCOM) terminal in two airline checkable cases.

Tested in several situations from missile ranges, extremely tough weather conditions, emergency and disaster response, and even deployed via para-trooper; each time the GATR-Com antenna performed beyond expectations.
