The VS30 Valcosphere provides capacitive "top hat" loading of any Valcom coil-loaded antenna in the following series:
Capacitive "top hat" loading provides increased bandwidth at the operating frequency.
The Valcosphere's special shape also affects corona discharge protection by preventing high voltage field concentrations at the antenna tip.
The copper plated steel elements are rapidly assembled via integral brass compression fittings. The resulting rugged structure is screwed into the tip of the antenna and secured with a locking screw.
