<p>[QUOTE="Dean Anderson, post: 399864, member: 8327"]I believe the "balls" on the lightening rods were for decoration only as the one piece rod goes through them, the rods aren't 2 pieces. so there's no way they could act as an insulator (40 years as a union electrician has taught me at least that much!). Maybe they were an indicator, because I'm sure if lightning hit the rod, the globe would burst and be gone. I've actually demoed some old lightning rods, as well as installed the newer high tech lightening systems, and they all have a cable going down and attaching to a ground rod, in the ground.[/QUOTE]</p><p><br /></p>
