Abstract
An antenna for use with portable radio and telephone equipment includes a main radiator and a shield plate. One end of the shield plate is attached to the outer conductor of a coaxial cable abutting the shield plate. The main radiator is attached to the inner conductor of the coaxial cable a predetermined distance away from the shield plate. The main radiator and shield plate are mounted inside an antenna housing. The shield plate includes a head section having a pair of deformable tabs forming a positioning clip for holding the outer conductor of the coaxial cable. The inner conductor of the coaxial cable extends beyond the positioning clip for attachment to the main radiator.
