That's not true at all. Anodizing merely adds a dye to a very thin
surface oxide. Aluminum oxide is going to grow naturally anyway, and
is essentially an insulator. Skin effect doesn't apply to a surface
insulator.

Yes, I have often wondered why annodized aluminum couldn't be used. I
assume there is a reason. But it would sure help make antennas less
conspiculous.

Why on earth would you want it to be shiny? Seems like it would be more
of any eyesore to any neighbors that way. It certainly doesn't make any
difference electrically.

Is there anything that will keep an antenna shiny and bright, besides not
putting it up?
I have often heard clear Krylon mentioned, but from my experience, it is
very short lived. Three coats, allowed to dry between coats only lasted a
few months if that.
Around here (central MI) the shiny Al turns to a dull finish in a month
or two.
Alodyne does last and looks good, if you like a shiny gold color and have
both time and ambition. I have used Alodyne on aircraft elevator hinges.
It's a very labor intensive (tedious) process. The antenna would certainly
stand out.
