A full-scale study was conducted by the Naval Air Development Center, Warminster, PA NADC, for the C3 Division of the U.S. Army Avionics Research and Development Activity AVRADA, Fort Monmouth, NJ, to test and evaluate production prototype antenna systems that essentially met the requirement for SINCGARS operation when installed on an Army UH-1 helicopter. The results of these tests determined a suitable tail whip antenna to be used on the UH-1 to satisfy the SINCGARS requirement between 30 and 88 MHz. This technical report describes the results of tests conducted on antennas manufactured by three major Airborne Antenna manufacturers, each of whom attempted to provide an antenna system that would directly replace the standard Army CU-942B antenna, and satisfy the more stringent requirements of project SINCGARS. The information in this report provides, in part, the technical data for the production data package of an adequate VHF-FM Communications antenna for the UH-1 aircraft. Keywords include Tail whip antenna Antenna couplers Straight whip antenna UH-1 helicopter and Swept frequency patterns.
