1.8 Antenna System

The GATR 1.8 antenna system can be utilized as a stand-alone terminal, or can augment smaller aperture systems (1.2 meter and smaller) while maintaining a small form factor. The smaller volume and weight of the GATR antenna system versus a traditional rigid dish allows it to be more easily transported. It can also be setup and on satellite in under 30 minutes, making it ideal in situations where infrastructure has been lost.

The 1.8 meter is primarily used in the continental U.S. and is available for X- and Ku-bands. For questions or to schedule a demonstration, Click Here to Contact Us.
