Abstract:
A method for manufacturing a protectively coated antenna including a helical conductor, the method comprising the steps of:threading a temporary support into the helical conductor with the helical conductor engaging threads on the temporary support, the temporary support including an asymmetrically shaped head;placing the helical conductor, while it is engaged with the temporary support, into an injection mold including an injection molding cavity, the injection mold including a recess outside of the molding cavity for accommodating the shaped head, the recess being shaped to orient the temporary support so that thermoplastic material is injected at a predetermined repeatable point with respect to the helical conductor;injecting thermoplastic material into the molding cavity;removing the helical conductor from the molding cavity; andunthreading the temporary support from the helical conductor.
