ABSTRACT:
The invention provides an antenna system for operation near a ground plane, for example, at or near the surface of a body of water. The antenna system includes, for example, an array of filar elements attached to one or more spiral elements. The system also includes, for example, a buoyant support and/or housing for transporting the antenna to and/or maintaining the antenna at or near the surface of a body of water.
