An antenna element has a stopper portion and a straw. For a vertical retraction and a slanted extension, the antenna element is movable between a slanted position wherein the antenna element is inclined from the housing when the stopper of the antenna element is positioned inside the angled tapered guide of the base coil and a retracted position substantially within the straw inside the radio housing wherein the antenna element is retracted vertically within the straw.
