Hi All,
I recently made a Moxon rectangle for 2 meters and used 1/2 inch copper
tubing for the elements. When finished, I polished the tubing and coated it
with a clear coat acrylic. It's a true work of art with shiny copper,
stained oak and brass screws for fixing but the acrylic is so brittle that I
can simply scrape it off with my thumb nail.
Is there another clear coat I can use that will be much stronger?
Polyurethane? Some form of epoxy? Or, does acrylic have some property that
doesn't affect/interfere/interact with RF?
Best Regards,
Jim, WP3JQ

Try relatively clear ship's varnish or what is sold as such. It's designed
for harsh weather protection and has no effect on antenna performance. I
have used the stuff on copper magloops. Keeps a nice appearance for ages.

Marine paints, epoxy paints, or if you want better radiation, black latex drive
coating stuff. Had bamboo poles coated with it, lasts forever (almost).
