Hello:

I've just received a 5BTV, 5 band trap vertical (75-10M), and as with
most of them, I would suppose the instructions suggest that ground
mounted is ok, but elevated it would be better to use radials.

I am planning on mounting it on the peak, near the center of a rather
large metal roof.

As others have mentioned, check the continuity
between the panels... some metal roofing comes
coated with plastic or paint (even if it looks galvanized).

If the skylights you mentioned interfere with
the ground connection along the peak of the
roof, I'd go ahead and run a strap down the
center of the roof peak line, bonding it to all
metal panels along the way.

Metal roofs can help, or hurt! If the connections
are bad between panels then you'll get loss and
noise. Otherwise, it's the best of both worlds, a
long-lasting roof that makes an excellent ground
plane.
