You may want to try a taller mast or move the antenna to the other side of the house to eliminate that reflection.
Of course none of that may work, but it needs to be eliminated and trial and error location testing is the only way to do it.

Thanks, I have read that the antenna should be installed 10 feet above the metal roof. Adding another 5 feet length is probably an easier change but my only concern there would be stability. Maybe I'd have to go to a larger mast.
I'm not seeing the fluctuation without the amp so I wasn't considering the roof being an issue. But I could be wrong.
