[TowerTalk] Fwd: Shielded shack

[Hans Hammarquist]

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).

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?
