I agree with Matt. Please don't pee on any equipment up there. The
discharge could be hazardous both directions. 5000 volts right through
the....well, I just hope you did not want to have any children after
that.

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,
