[RE-wrenches] Fwd: Grounding on a glacier??

[jason pozner]

Hey all,

I am trying to figure out how to mitigate problems found with a 12v 500w
simple DC system without a ground.  This system is at 14,500' on Denali (Mt
McKinly).  We experienced a somewhat "festive" fireworks display on the 4th
of July as static current from a storm seemed to travel through one of the
antennae, and energized some radio equipment.  There is no grounded
conductor, as there is no grounding electrode, as there is no ground to put
it in.  The camp is situated on about 500' of glacial ice.  The conductivity
of the ice is questionable, and to make the puzzle a bit more fun the camp
is raised and taken down at the beginning and end of every climbing season
(Apr-July), though the site is the same.  The loads are primarily for
communications for search and rescue purposes, and  reliability, and
simplicity are paramount.  I have been exploring the avenue of a surge
arrestorsThanks, and was wondering if any of you could make a recommendation
on a product that can either be reset or cheap enough to have a few
replacements on hand.  Everything is flown in or carried to the site, and
repair/replacement needs to be simple enough so non-technical minded
personnel can perform and re-set the system.

Thanks,
