Abstract: A directional locating device transmits pulsed RF signals at a stabilized frequency and is carried by an object the direction of which is to be determined from a distance remote from the transmitter. A one-half wave delay line in the receiver is responsive to the signal detected by a directional antenna for generating a 180 degree out-of-phase signal with respect to the signal detected by a sense antenna. A variable inductance coupling transformer having a primary winding is connected directly to the sense antenna and the output of the one-half wave delay line to produce at a secondary winding of the transformer a summation signal representing the summation of the 180 degree out-of-phase signal and the signal detected by the sense antenna.
