The reports you've posted show that you are down in a hole (so to speak). Signal levels in the are are predicted to be extremely weak. I would only consider using the largest, highest performance antennas available. Even then, you need some good fortune.
Mount high, and completely free of obstructions such as trees and buildings.
I would try the Antennas Direct DB8E or the 91XG to go after the real channels 14 and higher. The Antennacraft Y10713 is the only store bought antenna that has a chance at the real channels ranging from 7 to 13. Virtual Channel numbers have no bearing on antenna selection.
I would go so far as to install a PA-18 preamp on each antenna, then combine the UHF and VHF signals after the power insertion blocks that are indoors (protected from the elements). The idea here is to squeeze every last bit of noise performance out of the antennas and preamps. (Placing the UHF/VHF combiner on the output side of the preamps prevents the 1 dB or less insertion loss of the combiner from affecting the overall noise performance of the system.)
If you want to try a DIY antenna build, consider the GH10n3:

Having said all that, your posted reports force me to warn you that you may not get reliable reception at that location, regardless of the antenna(s) you choose. Be prepared to experiment with increased antenna mounting height... and alternate locations for the mast...
