Hi Partick,
I am not intending to protect my shack from a direct lightning strike. A direct
hit would possibly evaporate whatever is there. When my first house burnt down
after a direct hit there were no traces of the TV antenna or its mast the spot
where the lightning stroke. I have more stories (second hand) about rather
heavy wires disappearing from direct strikes.
This discussion has been going on for some time now and the conclusion is that
I am better off using a wire grid instead (which I will do).

Subject: [TowerTalk] Shielded shack
Gentlemen,
I am on the process to build myself a (small) free-standing shack next to my
tower. I am thinking (which usually is dangerous) that I should "dress" my
shack in aluminum foil, making it into a large Faraday Cage/shielded room.
By connecting the foil to the tower and make sure all wires entering my
shack enters through a (relatively) small window I should be able to make
the ultimate lightning protection.
What can go wrong with this? The foil will be connected through-out, walls,
floor, ceiling. All the feed-through connectors, surge protectors etc will
also the connect to the foil. I will using a wide aluminum strip to connect
the tower to the foil. Yes, the tower has nine (9) gounding rods, so I
believe that is OK.
Any feedback?
