Abstract
An automotive vehicle antenna comprises an outer cover having a cross section elongated in the direction of travel of the vehicle. The cover, which includes an enlarged section covering a loading coil, strengthens the antenna against bending due to wind force and presents a low wind resistance profile. The antenna may be window mounted and is provided with a conductive base engaging a conductive pivot support. The antenna may be pivoted to a flattened position to avoid damage by objects such as may be encountered in an automatic carwash. The antenna may be adjusted to a precise upright position for optimum reception and is adapted to return to a previously adjusted position when it is returned to the upright position from a flattened position.
