Welcome, kev23:
I suggest a Winegard HD7698P antenna and a preamp like the Channel Master 7778 or 7777. The 7778 is a medium gain preamp for most locations; the 7777 is a high gain preamp only for weak signal locations because it overloads with strong signals. I'm on the fence deciding which is best for you. You might be able to get away with the 7777 because of the trees.
I see only one strong FM signal that the FM filter in the preamp will probably take care of. I did an FM report based on my estimate of your location.

You can do your own report here to see how close I came. They don't link like the TVFOOL reports:

If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
More height would help. Try running your tvfool report at different heights to see where the signals become LOS.
This is what I got at 50 feet:

You can see how the signal grazes the terrain just before it reaches your antenna.
