I have just dismantled the base connectors from a vertical antenna which
has
been exposed to the elements for the last eleven years. The PL259
connectors
were protected using self amalgamating rubber tape covered with a double
layer of good quality black insulating tape.

The connector and all other parts covered with the self amalgamating tape
were all like new when the joint was cut open, with no signs of corrosion
or
moisture penetration.

External nuts and bolts were originally given a light covering of
vaseline/petroleum jelly and although slightly corroded, all turned
freely.

The system has been repositioned and reassembled using the same methods
and
works as good as new. I look forward to at least another another eleven
years of trouble free operating.

The tape I used was originally purchased from Tandy when they were closing
their UK branches (Radio Shack in the USA) but similar quality tape is
widely available from Maplin in the UK and other specialist electrical
outlets.

I've done the same thing, but with products more available to me. (Picked up
at Lowes or Home Depot).
3m makes a tape called "Scotchfil" which is self-amalgamating and very
waterproof, and is putty-like to conform to any shape,
and a weatherproof black vinyl electrical tape - 3M #88 which is great for
covering the scotchfil.
Then you can go one step farther by using "ScotchKote" which is like an
electrical varnish, to coat the plastic tape.
Vaseline on the bolts is a good idea, I had just squirted them with WD-40 or
CRC's equivalent.
I also use scotchkote to coat loading coils and exposed wire connections to
protect them from the elements..
