ABSTRACT:
A composite antenna element formed of a plurality of high modulus, high strength, low density, unidirectional graphite fibers bonded together by a flexible matrix material and formed into a tapered rod. The element is stored in a coiled configuration within a groove on the device to which it is attached and uses the strain energy stored within it during coiling to uncoil itself upon release into a vertical cantilever column on the order of eight feet high.
