Abstract
A thick folded dipole having an operating frequency which is far less than he first resonance frequency. The dipole includes a folded strand and a thick fed strand having a diameter which is about ten times greater than the diameter of the folded strand. The fed strand comprises two spaced apart cylindrical half strands having ends in the form of conical frustums and coaxial bore holes. A center conductor of a coaxial cable extends through the folded strand, the bore hole of one half strand, the space between the half strands and into the bore hole of the other half strand. Symmetrical spaced apart short circuits for matching the radiation impedance of the dipole by varying the distance between the short circuits are provided between the fed strand and the folded strand. In another embodiment there is disclosed a thick folded half dipole including a folded half strand and a thick fed cylindrical half strand.
