成果简介	NOVELTY - The finding antenna has a ground-based vertical thin vibrator with an upper capacitive load, complex impedances included in antenna breaks and counterweights placed on a ground. The upper capacitive load is made of three thin conductors connected to the upper point of the vibrator through series complex impedance. A vertical structure of the antenna is fixed on a 0.7 meter high heel, rigidly fixed to the ground, while the antenna feed points are located on the heel above the ground surface. The antenna is equipped with 8 counterweights. The conductors electrically connected to the lower ground housing terminal of the antenna feed, all counterweights have a length equal to 4.5 m, and are located on the ground in the radial direction from the antenna symmetrically around the circumference, the antenna is equipped with a broadband symmetrizing and matching device made in the form of two transformers with a volumetric coupling turn, a symmetrical two-wire feeder line and a feeder choke. USE - Direction finding antenna of decameter wave range with complex impedances. ADVANTAGE - The finding antenna ensures the preservation of the identity, stability and repeatability of the input impedance of the antenna, and also ensures the repeatability and identity of the phase characteristics of the direction finder in the azimuth and elevation planes, regardless of the characteristics of the underlying surface, on which the direction-finding array is located. The proposed useful model of the antenna, used as portion of wide-range direction-finding antenna arrays of the decameter wave range, allows for the practical implementation of repeatability and identity of the phase characteristics of the direction finder in the azimuth and elevation planes, regardless of the characteristics of the underlying surface on which the direction finder array assembled from antennas of the proposed design is placed. The finding antenna maintains the initial impedance characteristics of the proposed antenna during operation. The finding antenna provides simplicity and efficiency of assembly and disassembly of the antenna in typical field conditions of placement and operation.
