Abstract
An efficient and repeatable method for manufacturing a protectively coated helical conductor antenna. The helical conductor is threaded onto a temporary, removable support, such as a bolt including a shaped head and a shank having threads to hold the helical conductor. After being threaded on the bolt, the entire winding and the bolt shank are placed within an injection mold cavity. The mold also includes a recess outside of the injection cavity for accommodating the bolt head, with the recess being shaped to permit a specific orientation for the bolt. The shape of the bolt head and the recess define a repeatable orientation for the bolt and helical conductor. As a result, the point of injection relative to the helical winding may be exactly repeated time and time again. This allows selection of an injection point relative to the helical winding that produces minimal deformation, and the obtainment of consistent results thereby reducing variation and necessary manufacturing tolerances.
