Hi Greg, As I recall hearing it, the "cone of protection" is really just an area where the probability of a strike is much reduced. The "cone of protection" extends half as far as the lightning rod is high. If your rod was 800 feet high, the protection cone would extend 400 feet from the base of the rod in all directions. 200 yards is 600 feet, so I would consider that well outside of the cone.

Sometimes the "cone of protection" simply does not exist. A couple of weeks ago I had to respons to one of my sites which contains an 800 foot tower. While there a large storm cell developed and a severe thunderstorm ensued. Shortly before leaving lighting hit the tower which was unnerving enough. But as I was walking out the door to get in the truck, another strike hit the ground about 200 yards in front of me. So much for "protection."
