Ah, good. My suspicions were correct. I made my posts long because I thought you wanted to know the "why" behind an idea.
I suggest you purchase a variable attenuator and a few fixed attenuators. Experiment with them and then replace the variable and fixed with equivalent fixed if they help. They are not very expensive and you might learn something useful.
The link in my signature is about using an attenuator to test TV signals in the UK. They use the term DTT for what we call OTA.
I use a variable attenuator to test the sensitivity of tuners. I connect the antenna to the attenuator and then to a splitter to feed two TVs. I increase the attenuation to see which TV drops out at the "Digital Cliff" last; it's the winner. OTA signals are constantly changing in strength, so it doesn't work to remove the coax from one TV and connect it to the other. See attachment 1 for my test setup.

The idea that those weak stations may work better because of less overload from strong stations makes me want to attempt this at my house.

If the technique doesn't give improvement when increasing attenuation because you run out of weak signal, it means that the Dynamic Range is too great for the attenuator technique.
