Thanks for the details. Reception of WBNS will be difficult. I doubt that you will have 24/7 reception, but you might be able to receive it at times during Tropo season when it will be stronger than predicted by your tvfool report.
It is difficult to receive signals with a NM lower than -10 dB. If you are able to receive a signal with a NM lower than -10 dB, you have an excellent antenna system, your tvfool report is wrong, or they have been enhanced by Tropospheric Propagation.
The terrain profile shown by clicking on WBNS in your report isn't very encouraging:

Using different software for a profile shows interference to the signal from the curvature of the earth:
and the Longley-Rice coverage map shows that your location is in a dead zone for the WBNS signal:
However, if you are willing to take a gamble on a second antenna system for WBNS, with no guarantee of success, I suggest an Antennas Direct 91XG or DB8e with both panels aimed in the same direction and a preamp like the the Antennas Direct Juice or Channel Master 7778. If you also want VHF-High coverage for your second antenna, I suggest the Winegard HD7698P. If you want to experiment with a low noise figure preamp, I suggest the Kitztech KT-200, but you will need an outdoor housing for it. Low noise figure preamps can give a little more weak signal sensitivity, but they are more subject to static damage.
