I considered 2 antenna's briefly, but most of my research seemed to indicate that a two antenna solution could be fairly difficult to pull off.
Yes, difficult but not impossible. Sometimes you don't have many options. Two UHF antennas aimed in different directions are not easily combined, especially if you have a DVR.

One person I spoke with recommended the DB8e.
An antenna that has two panels that can be aimed in different directions sometimes solves the problem, but it doesn't work as often as the marketing guys say it will. It's trial and error. When the same signals from each panel arrive at the combining point they will interfere with each other if they are not in phase.

When Spring 2016 arrives and the mature trees in my neighborhood have all their leaves again, I am concerned that they could cause considerable multipath interference.
Trees can really mess with TV signals. See attachment.

Is there a two antenna solution you would recommend?
Two UHF antennas, like two 4221s or a 4221 and a 751. First you must be certain that each antenna gets what you want from its direction before you try to combine them.

You could have an A/B switch to select which antenna you want.

You could have one antenna go to the TiVo and one antenna go to the antenna input of the TV.

You could have a custom AC7 filter for real channel 38 from Tin Lee to combine PBS with the other channels, like mulliganman did.
