Our journey

A Legacy of Innovation and Excellence

Av-Comm’s origin stems from the aerospace industry with the company name originally standing for Aviation Communications, reflecting our first product, a low fuel warning system for Bell Jet Ranger helicopters developed by our founder Garry Cratt.
The businesses focus shifted when Garry’s hobby of Amateur Radio grew into the emerging technology of satellite television. Av-Comm then followed a natural progression into Broadcast Media, followed by Satellite Internet services, and now building, operating, and sustaining Satellite Ground Station infrastructure throughout the world.
