Lightning Master - Static DissipaterLightning Master Static Dissipaters lower the exposure to a direct lightning strike by controlling the conditions which trigger direct strike (i.e. they reduce the build-up of static ground charge and retard the formation of the ion 'streamers" which complete the path for a lightning strike).The Dissipater employs the point-discharge principle to continually leak off the lightning causing ground potential in low amperages over a long period of time instead of the short duration, high amperage discharge occurring with a lightning strike.This is the same technology from the same manufacturer which is successfully employed to protect commercial broadcast and television towers from direct lightning strikes. This 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.
