Don't try the last solution during an electrical storm.

Boy -- seems I recall a similar thread a few years ago -- might have
been grounding on sand? anyway, as I recall, the issue had to do with
bonding, and keeping things at the same potential (discharging
static?). I've heard of using bags of stuff over a copper grid / mesh
in RF broadcast and the ski industry. Might be some kind of copper /
salt stuff. I also recall someone suggesting peeing on a conventional
ground electrode? Good luck. db

NASA had a similar problem on the space station. They used (I
think - research this) some kind of static discharge unit on the
exterior of the station.

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,
Jay Pozner
