A fully collapsible, telescoping asymmetrically loaded half-wavelength vertical antenna. A base of the antenna formed of telescope sections, carries at its upper end an integral, coaxial LC matching network. Coaxially telescoped within the base is a mast formed of multiple telescoping sections, which may be extended and secured in sequence from the ground by an unassisted user. The matching network includes a coil wound concentrically about a form at the upper end of the base, the mast having a lower section telescoped within the coil by a controllable extent for providing preselected capacitance with the base. The upper end of the base serves as the feedpoint.
