Discone antenna
Abstract
Abstract The antenna structure disclosed is of the discone type and comprises six support towers arranged at the vertices of a hexagon. Active element supporting cables extend between the towers along the sides of the hexagon. A plurality of active elements radiate outwardly from a feed point located centrally of the hexagon to terminate on the supporting cables. The supporting towers are guyed by a plurality of guys anchored at six anchor points located on lines of intersection of vertical planes through the supporting cables. The guys extend outwardly of the hexagon within these vertical planes. The supporting tower and guying arrangement is extremely simple compared to prior arrangements. Furthermore, the feed point is supported above a platform raised above actual ground level and a plurality of ground wires extend radially outward of the platform and downwardly therefrom with the major portion of their length being buried beneath the ground. This eliminates problems of high frequency noise adjacent actual ground level and also eliminates problems of wind blown refuse, snow, etc., interfering with proper operation of the antenna. The antenna may be tuned by adjusting the height of the feed point above the platform and by means of a variable capacitor in the feed line to the antenna.
