Try aim the ANT751 at 83 degree magnetic compass direction , at K23HT-D REAL UHF Digital Channel 23 , virtual number (x) PBS.
K23HT-D is a repeater Tv station for KUID-DT REAL VHF channel number 12 , virtual number (35.1) Idaho , PBS.
KUID is further away and has 2 edge path obstructions = hills/mountains.
More on KUID later.

Looking at Pending Applications Included tvfool radar report and channel list , and , doing research using the google search box I found that ,
(( in the google search box , type in variations of the Tv station call sign , example , k23ht , k23ht tv , k23ht-d , k23ht-d 23 , and so forth.
The web sites that google will find that have the most Practical and Useful information that is Easy To Use , are , wikipedia and rabbitears.info.))
KXLY-DT channel 13 ABC and Me-TV.
KXLY channel 22 ABC and Me-TV.
KXMN-LD channel 17 Me-Tv.
So no requirement to receive , KXLY-DT channel 13.
_______________
KDYS-LP channel 32 , Daystar religion. Weak signal strength.
KQUP channel 24 , Daystar religion. Strong signal strength.
So no requirement to receive KDYS channel 32.
_______________
KWSU-TV channel 10 PBS.
KWSU-TV channel 17 , same PBS.
So no requirement to receive KWSU channel 10.
_______________
KLEW-TV channel 22 , is Very Weak Signal Strength.
And will require a Large UHF antenna to receive.
More on that later.
_______________
At this point , this eliminates the 2 extremes of directions of the , North East Digital Tv stations channels and South East Digital TV stations channels.
And the VHF Digital Tv stations channels with exception of , KSPS-TV channel 7 , Spokane PBS. KSPS is strong signal strength at your location.
__
This all being the situation , aim the ANT751 at about 83 degree magnetic compass direction , K23HT-D channel 23 PBS.
_______________
And now alternatives.
A better antenna for reception of the UHF Digital TV stations/channels and the 1 VHF Digital Tv station/channel KSPS-TV 7 PBS.
Is a Channel Master CM4228HD antenna , the CM4228HD is a High Gain UHF antenna and does a fair to good job of receiving the VHF high band channels of 7 thru 13.
Aim the CM4228HD at about 83 degree magnetic compass direction.
___
You can use the CM4228HD to Test reception of KLEW-TV channel 22 CBS , by aiming the CM4228HD at about 131 degree magnetic compass direction and at the same time will be Testing the reception of KUID-DT channel 12 PBS 138 degree magnetic compass direction.
__________________________________________________________
The ANT751 antenna can Test reception of KUID-DT channel 12 , PBS. 138 degree magnetic compass direction.
The ANT751 antenna can Test reception of KLEW-TV channel 22 , CBS. 131 degree magnetic compass direction.
____
Here is how to aim antennas ,
http://www.kyes.com/antenna/pointing/pointing.html.
As always , the starting antenna aim direction is the --> starting antenna aim direction.
The antenna aim direction can be adjusted for best reception.
Most Digital Tv's have a signal strength meter and some Digital Tv's also have a signal quality meter.

What is the make and model number of the 10 dB amplifier??

Also , Weather->Water , can get into the matching transformer that connects the ANT751 antenna to the coax.
Replace the matching transformer (balun) with a Channel Master CM-94444 matching transformer.
Also Water can get into the connections and coax that are outside , recommend replace outside coax with the coax that has the Compression type connectors on the ends of the coax , not the Old crimp type connectors on the ends of the coax.
And replace other connectors that are exposed to Weather->Water.
To make double sure that water does not get into the matching transformer and coax connection's , outside connectors , outside coax.
Wrap the ->Complete<- matching transformer the wires end , the body of the matching transformer the coax connector end and the coax , with , Coax Seal ,
http://www.coaxseal.com.
Wrap other outside connections etc. with coax seal.
___________________________________________________________
As always , trees and tree leaves , plants and plant leaves , do a good job of , multipath/reflecting , absorbing , blocking , Digital Tv reception and so do buildings and other obstructions including your own roof and building.
It is best to install or test antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own roof and building.

Digital Broadcast Tv Tuners can develop - Digital Glitches - that are not cleared out with simple channel scans.
Do a Double Rescan.
