But I have a hankering to use wooden insulators next time I put an
antenna up.

The old ARRL handbooks always recommended boiling wooden feedline
spacers in paraffin wax for weatherproofing. I suppose the idea is
that it's water-repellent. Don't know how long this can be expected to
survive weather extremes (ice, heat). In my experiments in my garage,
the wax coating seems to pretty much rub right off with my fingernail,
so I'm not sure how much good it does where the feed wires or tie
wires abrades against it.


Hi.
I think some Thompson's water seal would be a good substitute for the
boiling paraffin wax. I think the Thompson's is wax dissolved in
kerosene or Diesel. I have been putting two coats on some posts going
into the ground.
