Abstract
A dipole resonent loop antenna having a pair of semicircular, quarter-wave antenna elements curving away from each other in a generally circular configuration. The ends of the antenna elements are connected to each other through a pair of generally T-shaped insulative couplers having their center legs extending toward each other. A hollow boom positioned diametrically in the circular configuration has its ends secured to the center legs of the couplers. The center of the boom is then mounted on a vertical mast so that the mast extends generally along the axis of the circular configuration. A co-axial cable having a pair of conductors runs along the outside of the mast and passes into the interior of the boom through a center aperture. The conductors extend along the interior of the boom toward one of the couplers where they exit through an aperture in the outer wall of the coupler and are secured to respective antenna elements by screws passing through the coupler and the antenna elements.
