Forespar Performance Products 151100 Lightning Master - Static Dissipater

Lightweight (5. 2 oz. ) 21'' long Dissipater mounts to the masthead and extends vertically above all other masthead equipment. We do not claim that this product is 100% effective in preventing a lightning strike. At the present collective level of understanding of the lightning phenomenon, no one can make that claim. This product does control the causes of lightning strikes and thereby reduces the incidence of direct strikes.
