I will defer to ADTech for a final answer, but my opinion is the DB4E. The DB8E has more gain, but in a non-uniform field (because of the trees) a 4-bay antenna sometimes beats an 8-bay because it has a smaller capture area. An advantage of the 91XG is that you can tilt the front up slightly, to aim it at the top of the trees.

He might say if you can't get above the trees, forget it.

I hope you realize that we are now in an experimental area with no guarantees.

I like the Antennas Direct products because they are well made, they stand behind their product, and the DB4E doesn't have whiskers sticking out to poke you. Naturally, ADTech would favor his company's product, but he has enough integrity to recommend the best antenna for the job no matter who makes it.
