Abstract: A compact lightweight flexible omnidirectional broadband UHF antenna of the fat monopole type is disclosed. The antenna comprises a braided copper sleeve molded inside a truncated cone of neoprene rubber. The antenna is suitable for vehicle or mast mounting. When mast mounted, the antenna may be associated with ground plane rods, each of which is mounted to a common support by means of a pivot with yieldable protuberances. The protuberances yield to the plane face of the support and will, therefore, enter recesses provided in the support in the rotational path of the protuberances. When the protuberances enter the recesses, the associated ground plane rod is locked in either an operational or a storage position.

Abstract: A compact collapsible broadband directional VHF antenna is disclosed. The antenna is comprised of radiating elements consisting of rods in a Vee configuration, the rods being incorporated into a mechanism in which a series of insulating links are used to raise the antenna with a low and uniformly applied force. Associated with these are phasing elements physically shortened by capacitive loading.
