Hello, Kinetic:
You should get a good selection of channels if you use a Winegard HD7694P aimed at 66 degrees magnetic and the signal path is clear.(Corrected antenna model number)
An alternative might be the RCA ANT751, but I see a lot of trees in your area and the terrain in the signal path close to you is uneven.
Small changes in location and antenna height give a very different report. I don't have your exact address, but here is a report based on my estimate of your location:

moving up to 60 feet looks more like your report:

If KBVO-CD on real channel 31 gives you MyN, you don't need to worry about KCWX on 5 or 8.
You don't need a preamp if the signal path is clear in that direction.
If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
