[TowerTalk] Pelican case for outdoor use

[Grant Saviers]

I think they will work fine but an issue is the accumulation of 
condensation.  It is very difficult to make something with cables in/out 
to be hermetically sealed.  If a box is not perfectly airtight, moisture 
gets inside from air pressure changes due to temperature and barometric 
pressure and condenses.  In my NEMA 4 enclosures which are 
rain/splash/hose spray proof, a bug proof vent keeps the inside humidity 
level at ambient here in the very wet Pacific Northwest .  No 
accumulated condensation.  The Pelican seals are probably EPDM rubber 
which lasts a long time in window gaskets and are protected anyway.
