Metal Roof?
 

I'm mounting my antenna mast with an eave mount on my shop.
The shop has a metal roof, the antennas are on the front side of the shop and are not looking over the metal roof towards the transmitters.
The antennas have a direct LOS toward the transmitters any concerns with the metal roof behind the antennas?

Thanks in advance,
Charles

Mount the antennas at least 3' above the roof. VHF antennas might need a bit more.
