Joe,
I also use the plastic cutting boards for insulator material. I use the white
ones, they are about 3/8" thick.
I have been using them like you about 10 years and no problems from the sun.
Nice and easy to cut
and drill. I round the corners around the drilled holes so no sharp corners to
cut the antenna rope.
Great minds think alike :-)
