Abstract
A mobile antenna includes a radiating element and an inductance winding for tuning the radiating element for operation on a desired frequency. The inductance winding is supported within the base of the antenna by a core assembly and an overmold layer within which the turns of the winding are partially embedded. The winding is preferably formed with a relatively large diameter and of relatively heavy gauge wire, and the winding support core is preferably formed with a chamber concentric to the winding to improve the electrical efficiency of the winding, and hence the radiating efficiency of the antenna.
