A communication method successfully demonstrated using readily available amateur (ham) radio equipment with minor modifications, mounted on a tethered helium-filled balloon or high-lift kite to establish ad hoc two way radio communications in remote areas, radio dead zones and in the case of a repeater failure. Tested on both VHF and UHF bands, one person can setup in 15 minutes. Cost is approximately $2,000.00. Minimum wind requirement is approximately 6 mph for a kite. Maximum wind for tethered spherical helium balloon is approximately 20 mph.
