[Icom] Strike-O.T.

Thu May 6 15:22:11 EDT 2004

Back to protecting my 756 Pro II and 4KL ( hopefully Dick we are on topic ),
why doesn't a well grounded 50' tower ( two 8' copper coated rods 7.5' in
the ground attached to the tower ) act as a "lightening rod" protecting
other lower structures?

Most tall commercial structures seem to have lightening rod protection  (
the 19 story building I'm currently in for example ) and I've never heard of
a strike wiping out any of the building's electronics.
