Following are some links to information about "wire brush" static dissipators. It seems that cosmic rays produce the ionization trails that the static charge follows to produce lightning. You can't stop cosmic rays nor can you discharge a cloud or earth to prevent lightning. However, such devices can be used as lightning rods. They are about as effective as a single lightning rod in determining where the lighting is going to strike your tower or house. So if you use such a device you must have a hefty ground wire and ground to carry the current safely to the earth. Also, if lightning does strike the porcupine or wire brush there may be a hundred red hot needles (darts) shot in all directions when it hits. Could make things a bit exciting. http://www.cltskywarn.org/lightning.htm http://www.lightningsafety.com/nlsi_lhm/charge_transfer.html http://www.lightningsafety.com/nlsi_lhm/magic.pdf http://www2.slac.stanford.edu/vvc/cosmicrays/cratmos.html 73 Bill wa4lav At 11:19 AM 7/28/2004 -0400, towertalk-request@contesting.com wrote: Subject: Re: [TowerTalk] spider balls To: <Lew@dsl-only.net> Cc: 'Towertalk Reflector' <towertalk@contesting.com> Message-ID: <004301c474ac$35c16440$6e2d5044@homebrew1> Content-Type: text/plain; charset="iso-8859-1" _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
