Radio Propagation via Transponder.

Abstract

A UHF radio propagation experiment was carried out over the south-western U.S. in July, 1977. Radio signals were relayed between ground stations located up to 500 mi. (800 km.) apart by a parachute-borne transponder. The strength of the received signals was found to be in general agreement with calculations utilizing standard atmospheric refraction. The receiving sites for the experiment employed low-noise preamplifiers and custom-made helical beam antennas as well as standard Air Force communications receiving equipment. (Author)
