Circularly Disposed Dipole Array is a specialized antenna configuration used for radio direction finding. It consists of multiple dipole elements arranged in a large ring, often with a central reflector. By analyzing the phase and amplitude differences of a signal arriving at the various elements, operators can accurately determine the direction of the transmission source.
