The HD8200xl is not the right antenna for you. It covers VHF-Low real channels 2-6. which you don't have.
The HDB91x is also the wrong antenna for you. It would be OK for your UHF signals, real channels 14-51, but not so good for CBS on real channel 12.
I don't have any experience with the HDHorizonX10 antenna, and I find the advertising copy hard to believe. It's just another small inefficient antenna with integrated high gain amp that tries to make up for its poor performance. Some people find that type of antenna works OK for them, but don't get your hopes up.
Is this your test setup using one TV?
Ant > RCA TVPRAMP1R > 50 ft RG6 > power inserter > TV
If you have tried two antennas with that test setup for CBS with your antenna aimed at 41 degrees magnetic using a pocket compass, not a smart phone compass, and you still can't get CBS 100%, then there is something wrong with the equipment or it's the trees.
You can see you are on the fringe of coverage:
And you can see that the signal just makes it over the terrain:
Usually, a VHF signal can get over terrain like that better than UHF, so without any photos of your location, I think the nearby trees are the problem.
