All:
The Waxoyl product John (G3JVC) mentioned sounds like a good idea for
long-term protection against aluminum corrosion. It has an added benefit of
keeping ice from forming according to John.
I did a quick search for Waxoyl and it doesn't seem to be available at the
local hardware store hear in the U.S. Is there a clear Waxoyl equivelant
here in the states? If so, where?
One more thing, would a thin coating of a product like Waxoyl cause a change
in resonance with a Yagi antenna?
Thanks,
Tony KT2Q
Are there any resonance problems
John (G3JVC)
Waxoyl sounds like the solution for oxidation and corrosion. I'm putting up
a 5 element monobander on 20 meters so it's a fairly expensive investment
and would like it stay corrosion free.
I have a few more questions if you don't mind.
Do you think coating the entire antenna will change it's resonace?
