You'll need to consider mounting high enough to clear nearby trees. A quick look at the area near your location suggests it's heavily wooded. If you can do that, then I would suggest the following antenna system,
Antennas Direct 91XG or Winegard HD9095P (UHF, real channels 14 and higher)
Antennacraft Y10713 (High-VHF, real CH-7 through 13)
The UHF antenna should mount above the VHF antenna. At least 3' of separation is needed, but more would be ideal.
I would install an Antennas Direct PA-18 preamp on each antenna. Then cable each down separately to the power insertion blocks which are going to be inside out of the weather. At that point I would join the two antennas into a single coax using a UVSJ.
An alternative would be to use a single combination antenna such as the Winegard HD7698P or Antennacraft HBU-55
