Well, I'll tell you what you need to look at. First, check your chart, identify the channels you want. Make sure each has a positive value for the Signal NM - the higher the better your odds of tuning. Then you lump together the general directions of them all, which in your case, south pretty much covers it, with the exception of 24. Being that 24 is your best signal, I wouldn't work too hard to get it. The hope is that your antenna will be able to still pick it up even if you don't aim right at it. Now you look at the bottom tables that show if the signal is UHF, VHF-Hi or VHF-Lo. In your case, VHF-Lo isn't needed. Not all antennas are designed for all frequencies, so you'll need to make sure yours will get UHF & VHF-Hi (down to Ch 7). Then you have to consider your installation site - trees being the biggest hurdle. You'll want to have as clear of a line of sight to the south. Unlike satellite which needs open sky above, horizon is the best for an antenna.
Given that I don't know some of your factors, I think an ANT-751 would get all of those listed as LOS. Going beyond that, you'll start to see A/C indicators. So if you try to pull those signals beyond, you may get interference from the closer signals that are close or sharing the same Real channel. If you want to go a little bigger, maybe look at the Winegard HD7694p. The bigger the antenna, the better the range. You'll want to avoid too much range as you'll miss your sweet spot and start picking up stuff further south that could impact your closer signals. Again, that's where the A/C indicators on the left of the chart come into play. Think of it as you want to hear the conversation at your table in a noisy restaurant....not all the other chatter.
