I use "Plasticene" (maybe known as modelling clay?)
In my experience it never hardens, it is waterproof and easy to remove. I
used to use the orange tapered vinyl boots that were used on mineral
insulated "Pyro" cable over the top since they are a great seal over PL259s

I wiggle the connector as I finger tighten the barrel. The result is that they
are difficult to unscrew. Also I use a heavy silicone grease on the threads and
on the back where the barrel contacts the connector. I have never had any
issues with water in 20 years doing that.

I screw it down, wiggle it, back it off, wiggle it, push it down, screw it
down, repeat, then switch to Type N connectors (which don’t need any of that
nonsense).

Amen, George, on mating the “tiny indentations.” It’s easy to ignore this step
because many hams think they mate automatically as the PL-259 penetrates the
SO-239. They sometimes don’t. The coax itself has to be rotated back and
forth until the mating can be felt through one’s fingers.
One problem is that "finger-tight" is not the same for all hams.
The other is the use of off-brand connectors that do not fit well.
The other is that some connectors do not engage the protruding 'tabs' on
the PL-259 do not seat properly with the indentations on the SO-239.
Those are the ones
Years ago in a land far-far away all video coax connectors in Broadcast
Television were UHF (PL259).
We only tightened them hand (finger) tight. In may places pliers would have
not fit any way.
In black & white days we would want to be flat from DC to around 8 MHz with

I think he might have misspoken when suggesting using pliers to effect
an extra quarter-turn on a PL-259 after first getting it finger-tight.
The "quarter turn" idea most often refers to the trick of backing-off a

Thanks for all the responses and suggestions. I've decided to go with the
American Radio Supply covers, as they looked the best quality. I'll combine
them with some Scotch/3M/rescue tape/coax-seal, whatever I can source
locally. I would have gone with the PL-259 idea if I'd had any used ones

American Radio Supply sells metal covers that thread onto SO-239, and
have a soft rubber insert. I have been using them on outdoor connectors
for years now, and they work well...

Laziness maybe? Uninformed? I don’t know…frustrating for sure... I can tell you
that some people *IN* the US can’t get things shipped. I used to live in
Hawaii, its a state in the US, no customs forms, we’d pay the shipping, and
people STILL would not ship there.
Staggers the imagination.
This is frustrating for those of us who don’t live in the US or Europe. Even
