The UHF corner reflector antenna UHF channels 14 thru 51 is far to directional in the forward direction and is not designed to receive the VHF high band channels of 7 thru 13 for reception at your location.
I recommend a antenna that is far less directional and is designed to receive UHF channels 14 thru 51 and VHF channels 7 thru 13.
I recommend a ANT751 antenna aimed at about 347 degree magnetic compass direction. Here is how to aim antennas ,
http://www.kyes.com/antenna/pointing/pointing.html.
The ANT751 antenna has some forward direction antenna gain and also receives at the , front angles , back , back angles , directions of the antenna.
The Tv stations you are after are to the , north east , east , south west , north west.
Install the ANT751 in such a manner that the reception is not reduced or blocked to the , north east , east , south west , north west.
Looking at the Pending Applications Included Digital Channels list , the Tv stations in the Green and Yellow reception zones will be received , and some of the Tv stations in the Red reception zone at 347 degree magnetic compass direction should be received.

Install a Antennas Direct CPA-19 preamp.

For one Tv connected use no splitter.
For 2 Tv's connected use a , HFS-2D , 2 way splitter.
For 3 Tv's connected use a , HFS-3D , 3 way splitter.

As always , trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions.
It is best to install the antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception.
The Tv/s Must Channel Scan for the Broadcast Tv Channels , sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv trensmissions travel through thje air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for cable tv channels.
If the Tv stations to , north west , are not that much interest to receive (they are more of the same networks such as , NBC , CBS , ABC , etc.) then aim the ANT751 at about 64 degree magnetic compass direction.
With the ANT751 antenna aimed at 64 degrees magnetic compass direction , that will put the Tv stations to the north west , on the side of the antenna.
The Sides of a Tv antenna is where the least amount of reception takes place.
