When you click on the call-sign of a station listed on your TV Fool report, you get a view of the path profile, a graphic of the terrain cross-section between the transmitter and your location. In the case of the signal coming from 138° magnetic, you have some high terrain relatively close to your location. That suggests you'll be facing some significant challenges to reliable reception of those signals.
I would expect to need the largest available UHF and High-VHF antennas available. You'll also need to take steps to get over or around trees. Antennas such as the Antennas Direct 91XG, DB8e and Winegard HD9095P come to mind when looking for UHF solutions. The Antennacraft Y10713 and Winegard YA1713 are options for H-VHF coverage.
If you're into 'roll-yer-own' antennas, the GH10n3 is an amazing bit of engineering...
