I know a couple of RF engineers who swear by these and will not setup a
tower without them. We are looking at putting small ones on each end
of every row on a large array next year.<br>

They used (I think - research this) some kind of static discharge unit
on the exterior of the station.<br>

Hey all,<br>
<br>
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.<br>
<br>
Thanks,<br>
