Re: [IRCA] WATERPROOF BOXES (was: DKAZ questions)

In the electrical engineering world, it is considered mandatory to have holes (unless everything is potted) and they are referred to as weep holes.


For potting, RTV sealant of the type without acetic acid is the best choice. It's readily available and cheap.

One thing that will interest me is whether you get condensation
inside those sealed boxes Mark and Guy.    Over the years, a number
of radio amateurs have found they needed to add bleed holes on the
underside of the box to allow condensation to escape, at least for
long term deployment.

I believe the problem is that moist air can find its way into the
box, even if actual moisture can't, and then it gets cooler and the
moisture condenses and has nowhere to go.

It's a battle!

I've sealed up regular plastic boxes over the years with a runny
silicone compound used for sealing windshields (auto supply stores
have it, Permatex is one of the brands), figuring I won't be taking
it apart except in direst circumstances.  Then I have had to add a
bleed hole anyway.

best wishes,

Nick
