Next question: Will you be feeding a DirecTV DVR?
If you are feeding a DVR, then you need to consider your antenna options without
a rotor. (So far as I know, DirecTV's DVR has no provision for rotor control.) Based on your TVFool pattern, you should
have good results with a 4228 pointed at the WLAJ tower.
You will be aimed slightly away from the WKAR and WLNS towers, but they are closer to you and the 4228 has a decent side lobe for gain in their direction if you are aimed at WLAJ. The 4228 is also a good choice for this market because it has decent gain for VHF-Hi and the nearest NBC affiliate is on physical channel 10.
If you decide to go with a VHF antenna for WILX and a UHF antenna for the other channels, you might want to consider a pre-amp. The Channel Master 7777, for instance, integrates the combiner. (It has both a VHF-in and a UHF-in 75ohm F-connector.)
