"Richard Harrison" wrote in message ... Height is shown to attract lightning bolts to grounded towers used for various purposes. Many are hit by nearly every passing thunderstorm. Towers take lightning bolts. They don`t always if ever discharge the earth and atmosphere in their area to eliminate hits. They do seem to divert strikes in their vicinity and offer some protection to their surroundings. I`ve spent years in broadcast plants and seen many lightning strikes. If you build it they will come. Best regards, Richard Harrison, KB5WZI Saw a program on lightning a year or so back that described the mechanism involved in setting up a lightning strike. Every raised object in a fairly large area below an accumulating cloud charge sends up a stepped "leader"of opposing charge, all these "leaders" advance in steps that also zig and zag randomly upward. If I remember correctly the charge in the cloud is also sending out multiple feelers in a zig zag process. When one of the clouds feelers completes a circuit by meeting a leader from the ground the circuit completes and all hell breaks loose. It's all relatively random and the leader from a golfers head may just connect before the leader from a much taller tree or tower connects. if he's a lucky golfer the taller stuff will make the connection. I've seen weather service warnings lately indicating that anything within a 25 mile radius of a stormclouds center has a chance of winning the electrical lottery. When I see lightning as I'm mowing my 7 acres here in southern Oklahoma, I now shut down and make for the house.If I have an inkling we're gonna see weather I bag the terminal end of my various coax connections before the weather starts and coil them outside away from the house Harold KD5SAK |
