I gave up on AT&T because they could not make DSL work and every repair on the trunk line made it worse.
That sounds similar to the problem I had: Old neighborhood and not enough copper pairs. Now that the people are moving away from POTS lines to cellular and fiber, the likelihood of getting any help with copper is non-existent. A repair request for a copper pair is now weeks away in my area, even for a business.

Default Did you eliminate possible issues?

If you have not already done this you should try it just to prove the concept.
Disconnect the cable completely and run the same transmitters the same way with no cable.
if that shows no signs of interference plug in a small local antenna like the ones you see for sale everywhere or even just a short length of cable with about a foot of shield removed.
try all you can to make the same reference happen without being connected to the cable.
And do this with and without the cable box inline. I would start with just the tv itself to make sure the tv isn't just very sensitive to stray RF
This could give you an idea if the interference is being delivered by the cable or if there is a weak link in the equipment TV, Box etc
