WebA radio direction finder consists of a radio receiver, a directional antenna, and some other specialized equipment. With RDF equipment, the approximate azimuth (bearing) to a transmitting radio can be determined. One azimuth gives a general indication of direction. The intersection of two azimuths by different RDF stations is called a cut and ...
