Abstract
The present disclosure describes an antenna which may be collapsed and stored in a compact configuration and readily released from storage to assume a deployed operative state. More specifically, the antenna is a wire member comprised of a straight section and an integral transverse helical spring section. The antenna lends itself to storage about the axis of a right circular cylinder while permitting full deployment parallel to the longitudinal axis of the latter. This arrangement permits the storage of potential energies of torsion and bending respectively in the helical spring and straight portions of the antenna, and permits continuous motion in these planes to effect antenna erection and deployment.
