Abstract
An antenna linear extension and retraction apparatus and method of use for a submersible device is provided. The apparatus includes a body having a cavity formed at an external surface. A bladder containing a core material is arranged within the cavity. The core material contracts and expands the bladder depending upon a pressure that surrounds the bladder. An antenna is operatively connected with the bladder and moves between a retracted position and a deployed position as the bladder contracts and expands.
