For better reception of the groups of Digital Tv stations that are to the , north/north west , west , south west , south , south east , east.
Aim the HD7694P antenna at about 200 degree magnetic compass direction.
Here is how to aim antennas ,

This will improve reception of KKAF-CD UHF channel 33 and will put the groups of digital Tv stations at angles to the Tv antenna.
With the antenna aimed at about 150 degree magnetic compass direction that puts the Tv stations to the west and east , on the sides of the antenna , Tv transmitters that are on the sides of a antenna have the least amount of reception.
It is better to have the Tv transmitters at the front of the antenna and then the back of the antenna and then angles to the antenna. Or angles and then back.
