I have created a website for computer and radio geeks with many
columnists that are CB/HAM guys. I know there have been several
questions about lightning protection in the past and one of the
colmunists just wrote an article that explains it in a pretty simple
fashion (although it references computers in the example).
You can get to the article by going to
http://www.aboutgeeks.com
and looking for the article on 'Lightning Protection' on the home page.
BTW, aboutgeeks.com also has product reviews and technology news for
those interested.
Thanks
