The RC-292 is a general-purpose, stationary, ground-plane antenna used to increase the transmission/reception range of tactical frequency-modulation radio sets. The radiating and ground-plane elements must be adjusted to the proper length for a particular operating frequency. The RC-292๏ฟฝs technical characteristics are: frequency range, 20-76 mhz; planning range, about twice the planning range of a radio set using a quarter-wave whip antenna; height when erected, 11.28 to 12.56 meters (37 to 41.2 feet); and weight, about 19.5 kilograms (43 pounds).
