Abstract: Directional antenna comprising a cylindrical skirt and a base perpendicular to the skirt axis, and a unipole extending from the base along the axis and out of the skirt. Electrically insulated fixing means extending through an aperture in the base fix the unipole to the base. A coaxial feeder line extends through the skirt and has its inner conductor extending through the insulated fixing means and connected to the unipole through the aperture and its outer conductor connected to the skirt. The unipole has a length of
