Dipole antenna rod elements secured in support sleeves - are mounted using radial pressure against elastic plastics sleeves to permanently deform rod ends in sleeves

摘要

The rod elements of the antenna are inserted in a sleeve-shaped receptacle of the respective support. The metal rod end is permanently deformed by radia pressure onto elastic receptacle. Then the resetting force of the receptacle sleeve secures the rod end firmly and positively. The rod element has a notch (4) at the end (3), providing in the direction of the radial pressure. During deformation of the sleeve end the notch forms a hook engaging the material of the receptacle (6). The notch may be formed by lateral recesses on the stamping blank used for the production. Typically the receptacle is formed in one piece with the rod support, of elastically deformable plastics.
