Excellent reasoning - I guess I should have thought about how enameled
copper wire makes an excellent radiator.

Only the surface anodizing is an insulator. Radio frequency-wise, it
may just as well not be there leaving the high conductivity aluminium
siding to behave as if the anodizing didn't exist.

If the siding was covered with a 3" layer of plastic it still wouldn't
make any difference.
