[TowerTalk] quick waterproofing for PL-259 connectors?

[Jim Lux]

I'm looking for good ideas on how to waterproof a PL-259/SO-239 type
connection (say, a pair of PL's with a barrel in between) for temporary use.
There's lots of good ideas in the archives for permanent installation, but
what I'm looking for is something for a portable/field day operation.

1) real fast to mate (ideally, no extra time over what it takes to mate the
connectors)
2) cheap
3) real fast to demate
4) Ideally, no consumables
5) Doesn't require tools
6) Can be done in the dark/rain

Maybe something like a rubber boot that goes over the connector? (but how
does it seal on one of the ends?)

I'm interested in ideas for the "extension cord" (cable to cable) and the
"wall socket" (cable to equipment) usage model.

For the chassis mounted application, "rain tight" might be good enough (i.e.
it doesn't have to tolerate immersion), but for the cable to cable
application, water/mud/dirt proof is desirable.

While I'm thinking about it, ideas for waterproof or raintight 12VDC power
pole style connections and Cat5 networking would also be useful.
