As always , trees and tree leaves do a good job of , reflecting , reducing , blocking , Digital Tv reception and so do buildings and other obstructions including your own roof and house.
It is best to install a 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 house.

Removing the Reflector Screen allows the UHF reception loops to receive more signal at the 'back' of the antenna.
With the Reflector Screen on , the UHF reception loops receive more signal toward the front of the antenna but less at the back of the antenna.

Most reception situations , 1 aim direction will receive all the Tv stations.
However , some reception situation , antenna aiming is Experimental.
Most Digital Tv's have a Signal Strength Meter and some Digital Tv's also have a Signal Quality Meter.
Digital Broadcast Tv tuners can develop , Digital Glitches , that are not cleared out with simple channel scans.
Do a Double Channel scan.

KCWX is transmitting on VHF low band channel 5 , the VHF low band channels are 2 thru 6.
The CS2 UHF channel 14 thru 51 , and with the VHF reception rods channels 7 thru 13 , and is a small antenna.
__________________________________
If not able to get the small CS2 with the VHF high band reception rods to receive the Tv stations.
Will need to go to a Bigger antenna for better reception of the , VHF high band channels 7 thru 13 , and VHF low band channels 2 thru 6.
And might need to go to 2 antennas.
However give the CS2 with the VHF high band reception rods , a good try first.
