Abstract
A base insulator design for VLF antennas. A surface insulating material, h as glass, serves to provide a long surface distance between the upper and lower metallic components of the base. A thin, soft metal cover extends the base metal conductor out to the edge of the outer insulator and also provides a weather shield for the internal components. An insulator core of porcelain serves to take up all of the mechanical stress in the structure and a dielectric fluid serves as a coolant which also protects the inside surface from contamination.
