I expect that aiming the ANT751 antenna at about 65 degree magnetic compass direction ,
Will receive , K23HT-D REAL Digital UHF channel 23 , virtual number (12.1) PBS and the other Digital Tv stations/channels to the , north east , east , east south.
Here is how to aim antennas ,

_______________________________________
There is no requirement to receive , KWSU-TV channel 10 PBS because it is also transmitted , KWSU-TV channel 17 at 50 degree magnetic compass direction.
No requirement to receive , KUID-DT channel 12 PBS.
And no requirement to receive , KLEW-TV channel 22 , it is far to weak and will not be received any way.

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 locate the antenna at a location that has the least amount to no amount of obstructions in the directions of reception.
