theres varying claims on tophats and ball tops and stuff on top of cb antennas and and how effective they are . i was wondering what yalls experiences are with them ? from what i can tell most cb antenna builders claims about them lowering TOA and such are , guestionable , because theyre just too small to have the effect they claim on their antennas . i have read that they can be helpful to make an antenna less attractive for a lightning stike because they spread the elevated attracting charge out over a larger surface area so its not a such a little hot spot up there . anyhow , whats your experiences , thoughts and knowledge on them on or around 27 MHz. ?
