[TowerTalk] Fwd: Bulkhead feed-through.

[EZ Rhino]

If vapor is coming through from the inside, that means you're losing heat!  Not good.   Coaxes should come through the wall in as little a pipe/cutout/hole as possible.  Stuff rags in the void to keep cold air out, or if you're really serious, use expanding foam insulation from Blowes or Home Despot.  Other ideas including really cool entry panel boxes on my website  http://www.kf7p.com/KF7P/EntrancePanels.html  (shameless self plug :-)

Usually the bulkhead is on stand-offs so the plate is off the outside wall. Only 
coax goes thru the wall. There should be no vapor going thru the coax so no 
problem.
