[TowerTalk] Shielded shack

[Grant Saviers]

If it is lightning protection and not RFI shielding that is desired, 
then what is done for explosive magazines ought to be enough!
http://www.seftim.fr/publications/DDESB/17-3-LIGHTNING_PROTECTION_FOR_CRITICAL_EXPLOSIVES_OPERATIONS.pdf 
has many references, but there are older documents I've seen in prior 
google searches.  e.g. http://www.apd.army.mil/pdffiles/p385_64.pdf  Or 
standards for protection of petroleum storage facilities.

I would also think that foil is a bad choice as a conductor should you 
have a strike when #2 or larger is what is commonly used in large 
structures frequently hit.

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.
