Have you tried putting up a cheap HD broadcast antenna? Lots of old westerns and shows if you can pick them up. And no tin foil on the rabbit ears needed.
I have one. Sometimes we can get two or three channels but I live in the backwoods of TN in a deep valley between two high hills. We can’t even get anything with a regular antenna. It’s discouraging.
One thing I might do is switch to Dish Network if they carry his shows. I think it might be close enough to operate that he won’t struggle as much as something totally foreign.
In good weather I’m outside most of the time and don’t watch much TV so I’m not picky about changing. I do need to keep his shows.
