The invention relates broadly to a foldable antenna structure and specifically to a novel locking hinged joint that supports the antenna arm or element when in extended use and that permits folding of the element to a position along the mast. The hinge is of tubular configuration which cooperates with a spring loaded antenna element to maintain it in fixed position when in use and further to allow the element to be folded along the side of the mast. The joint of the invention also provides a secure, direct and effective electrically conductive path for the transmission of RF energy. Author
