Abstract
A double shot antenna comprising a cylindrical coilform having first and second ends, and inner and outer surfaces. In one form of the invention, the inner and outer surfaces of the coilform have helical grooves formed therein which extend from the first end of the coilform towards the second end of the coilform. The coilform is comprised of a first material which resists metal plating. Plastic material is positioned in the helical grooves with the plastic material being plated with an electrically conductive material to form first and second radiating elements. A connector is provided at the first end of the coilform which is electrically connected to the first and second radiating elements. The method of manufacturing the antenna is also disclosed.
