Your strongest and most plentiful stations are likely to be those that
serve the Grand Rapids market from your South southwest. You need to
determine in what direction are the trees closest to your home and likely
antenna. If that happens to be South southwest, you'll need to either cut
them lower or possibly look at stations from other areas.
I would consider a VHF/UHF antenna on a 10 ft mast to start, aimed at
the direction above. Keep the cable under 50 feet if possible and use
a good RG6. I would consider:

as your best and lowest cost option. If you receive those channels
from the South southwest, only then, you may want to consider a rotor
and possibly some kind of amplification. Before you make a rotor/amp
purchase, I'd think you would want to manually rotate the antenna in
different directions to see what you receive. Additionally, you should
only drive ONE television to start. That gives you some basis to see
what works, what helps and what makes things worse.........
Let us know what you decide to do.....
