Abstract
Abstract A flexible tubular antenna is coiled and stored inside a nose cone, and released through a rear door by spring or fluid pressure, applied as necessary to uncoil the antenna and maintain rigidity. The antenna trails behind the cone a sufficient distance to remain effective during the reentry period. Cooling is supplied by an outside layer of ablative material.
