Abstract (en)
An antenna mast incorporates a single strand of spring wire wound into a closed coil section at a base or bending fulcrum of the antenna mast. This closed coil section acts as a straight section of wire, for purposes of RF reception characteristics, when the antenna mast is not deflected. A center strand of wire enters and exits the closed coil section from opposite sides, reducing conductive length changes attributable to flexion of the antenna mast. As a result, tuning of the antenna mast to specific frequencies remains relatively stable even when the antenna mast is deflected, for example, by wind deflection forces or by contact with objects.
