The Army has a number of DF systems to locate enemy ground radio transmitters for example the PRD-1 HF Direction Finding Radio used in Korea and Vietnam Radio Receiving Set ANTRQ-23 which uses the OE-4GR antenna group.

Example of radio direction finder. Examples of radiolocation methodologies that do not produce bearings Manual handheld antenna sweeps as opposed to taking bearings Non-directional amplitude comparison heat maps Time difference of arrival. Radio Direction Finding Equipment One of the earliest military applications for radio was in direction-finding DF which makes it possible to locate the positions of enemy aircraft and ships using four major components. Some ships also received a Huff-Duff radio direction finder on a short mainmast.
