[TowerTalk] TowerTalk Digest, Vol 100, Issue 30

RE: Sealed Container for housing tuner, etc.  Those plastic electrical boxes work fine and, for smaller housings, the cast aluminum project boxes work nicely.  I utilize a little RTV to seal unwanted openings or leaks.  You can also install a tire valve assembly available at your local auto supply store and put a few pounds of positive air pressure in the box to prevent moisture incursion.  You might still get some condensation, however.  YMMV

The TUPPERWARE containers lasted about 2 years at my QTH, then they got brittle
and cracked apart... but for $9 was a good try!
The grey plastic electrical boxes available at Lowes / Home Depot for about $25
might be a good bet...
They come with a rubber seal around the edges of a lid that screws on tight...
BUT... you need to put an opening for the cables... suggest you simply cut a
hole in the BOTTOM...
Perhaps glue a PVC pipe section into the hole if you want more than that...
Tightly sealed containers can lead to pressure differences with temperature and
barometric changes, and a hole lets the water from condensation OUT!

Last summer, I replaced all the TUPPERWARE boxes that surrounded junction points
at the base of towers, and installed these boxes around coax switches that were
out in the weather for 5 years...  If the tuner fits in it OK, you will probably
have a good choice there...
