[TowerTalk] Fwd: Fwd: Bulkhead feed-through.

[Chris]

So here's what you do:  Keep the plate on the exterior wall over the hole, and add another plate on the interior wall.  Fill the space between the two plates with insulation, and replace your short bulkheads with the really long ones that will extend all the way through the wall, through both plates.

All the connectors are open to the air in the shack. I thought it was an excellent idea but realize now that it might not have been that excellent after all.

If (I am sure it will) the condensation goes through the connectors I will also have water on the outside with following corrosion. :( As the connectors are sealed, the water will have no way to get out.
