[TowerTalk] ABS Weatherproof Boxes

[Mike Fatchett]

HRO stocks various lengths of "barrel"/bulkhead connectors for PL-259's with
nuts on both sides.

Further to this topic from the other day, I just wanted to mention a
caution.  I use several of these for various antenna-related relay
switching, and found out the hard way that their wall thickness can be a
problem.  I wanted to use single-hole SO-239s in one box, and found that the
ones I could get had the thread on the outside - so you would stick them
through the box from the inside, and then put the nuts on to hold them in
place.  The trouble was that with the thick walls, the depth of the thread
remaining was insufficient to pull standard PL-259s down tight against the
jacks.  Intermittents galore till I figured it out.

You *can* get SO-239s that have the thread behind the fixed flange, but I
suspect you will have to hunt a little harder for them, and ask
specifically.  Also anyone hoping to mount Polyphasers directly on the wall
of the box may run into the same problem I did.
