OK guys, along this same line, I have a VHF all copper J-Pole and plan on
building UHF all copper J-pole.
Is common clear lacquer OK to prevent corrosion on the copper elements? I have
used automotive type black silicone under 2 wide electrical tape to seal
connections and the coax itself. The Coax to antenna connectors have been
soldered to the copper tubing after finding best SWR.
Other choices, Clear enamel, colored lacquer/enamel etc. Other stuff I have not
even thought of?
mainly just stop the copper from turning green but don't want to mess with
the antenna in any way. This will be used beside my house and not at some far
away repeater. Limited life is OK so long as I am aware of limitations.

This painting of antennas seems to be on many of our minds.
Wonder what the antenna manufactures would recommend or what they use if any???
After you get beyond the sales person who swears their products are rock solid
and don't need painting or additional protection then you might get someone who
would give some info.
I would hope they would have done testing for anything they recommend, both SWR
and pattern and signal.

and Krylon
Funny you should mention Krylon... although I haven't done so in recent
years, I used to Krylon (clear) all antennas and never had a problem. I
forgot all about that until your mention of it. And they were mostly UHF
antennas - beams and folded dipoles. Go figure.

I constructed a 6 meter beam some years back, worked like a bomb
even at 25ft above ground elevation. To ensure my pride and joy
would last a long time I sprayed it with clear Krylon brand spray
paint.
The antenna was instantly unusable regardless of my efforts to
remove the paint, re-tune or otherwise modify the antenna. I later
learned that type of paint contained materials with a horible
D-Factor. I was never able to use the antenna again, although it
remains in my back yard as a reminder.
