Abstract

A dipole antenna and a feedline therefor both formed from coaxial line. The dipole coaxial line has the jacket removed from a central portion thereof to expose the outer conductor which is there severed and spread apart to form a gap exposing the dielectric layer, the lengths of coaxial line on each side of the gap comprising dipole elements. The feedline has the jacket removed from one end portion thereof with its inner conductor being connected to the outer shield conductor of one dipole element on one side of the gap and the outer conductor thereof being connected to the outer shield conductor of the other dipole element on the other side of the gap thereby to form center feedpoint connections between the feedline conductors and the dipole elements. Clamping means comprising a pair of relatively thin flat clamping members of substantially rigid insulating material are provided to be fastened together face to face with the feedpoint connections and adjacent coaxial line portions therebetween. The opposing faces of these clamping members are formed to provide a central cavity for receiving and completely enclosing the center feedpoint connections therein and plurality of passages radiate from said cavity for receiving portions of the dipole coaxial line on opposite sides of the gap and the portion of the feedline adjacent the center feedpoint connections.
