Watching and learning from this thread, I'm beginning to think I should be
operating from a metal dog house with a ring of ground rods directly at the
station equipment (sarcastic). I've got about 6' of ground buss running
behind the operating position. Total distance to the rod is about 6'-7'. I
fail to see how it can get any better than this, short of the metal dog
I think what all respondants to this thread are saying is that if you get a
close strike, you are TOAST! Trying to engineer for a direct hit is
impossible with the light gauge metals and structures that are quite flimsy
when compared to a bridge or a sky-scraper.
How about some practical advice for the 90% of hams that cannot possibly
engineer a perfect solution. A second floor shack is TOAST. What should
this guy do to protect his family and possessions? Forget the radio! I'd
expect a sensitive piece of equipment to fry in the presence of a million
volts at a million amps. I would rather have that insured equipment
completely melt down and fry while shunting most of the strike to ground
rather than burn 100% of my worldly possessions.
