Multi-band, variable, high-frequency antenna

Abstract

A multi-band, variable, high-frequency antenna comprises a pair of transmission lines for conveyance of signals from and to a transceiver, and a pair of braided copper conductor elements, each in electrical communication at a proximal end thereof with one of the transmission lines. Each of the braided copper conductor elements is mounted on a non-conductive support cord, the braided copper conductor elements being expandable and retractable along the support cords on which the conductor elements are mounted. A cord lock is proximate a distal end of each of the conductor elements for releasably locking the distal end of the conductor element at a selected position on the support cord on which the conductor element is mounted. Release of the cord locks permits lengthening and shortening of the braided copper conductor elements, and locking of the cord locks is operative to lock the conductor elements in place on the support cords to selectively fix a length of each of the conductor elements.
