DIRECTION-FINDING ANTENNA SYSTEM Russian patent published in 1995 - IPC

FIELD: electronic engineering. SUBSTANCE: direction-finding antenna system has two pairs of vertical non-symmetric vibrators and two pairs of horizontal symmetric vibrators connected with the primary windings of transformers. The expansion of the range towards low frequencies and the increase of the equivalent effective height of the system are achieved by means of the choice of the distance between the vibrators, of the lengths of the vibrator arms and of the method of their connecting up to the transformers as well as by means of introducing two-channel active members and parallel summators. The system is designed for finding the direction of radiosignal coming. EFFECT: expanded range of the system operation and the increased height of the system. 2 dwg
