I know on houses we use lighting rods that are about 1/2 thick and about 18 inches long and are attached to a 3/8 braded copper wire that runs to a ground rod and the guy who installs them said when they are hit the wire is vaporized form the voltage , so basiclly there only good for one strike. average size house cost about 4500.00 to supply and install.
