Without any direct experience, other than a trap vertical on a 20 x 40
metal roof made up of 4x8 metal sheets, I'd say a vertical would work
fine, but anything else nearby could be adversely affected. I also
wonder, at least in theory, if you wouldn't risk imperfect electrical
connections between shingles becoming harmonic-generating diodes, in the
presence of a strong RF field.
