ABSTRACT:
A floatable radio antenna (releasable from a submarine) includes a solid hemisphere of conductive material concentric with a hollow hemisphere of dielectric material. The hemispheres are contained in a floatation jacket which carries them above the surface of a liquid on which the jacket floats. Concentric spheres may be used if desired. The dielectric material permits an antenna of small physical dimensions.
