Analogue signals passed through trees, but the digital signal passing through tress, especially through pine trees, won't be strong enough to be decoded by the digital tuner. With your antenna aimed as it is, you're going to have to live with the wind-fade problem.
Depending on where you live, you may try picking up your signals bounced off something like a building. Multi-path (bounced) signals can be as strong or even stronger that line-of-sight. This is a long shot, but if this is a real problem, try a different direction.
