I was at a campground earlier this year and had issues with the cable TV as they are all digital cable. I struggled in my 2017 Newmar Ventana to get a good picture on all TV's and there number of channels being detected in the channel search was inconsistent. It was time to investigate.
There were a couple of issues going on and I'll keep this post brief as this is a very simple situation. First thing is to find your coax splitters if you have any. In my coach there is a 1 in 4 out splitter in the bay just forward of the pegboard. There is a 1 in 2 out under the kitchen sink on the back wall.
Issue 1: Unused ports were not terminated. I bought terminators from Amazon to terminate the unused ports

Issue 2: The coax splitters used had a narrower frequency band that likely did not play well with digital coax and 4K signals. I swapped both splitters out

Notice these are 5-2000 Mhz vs. what's printed on yours.
After the above my coax issues went away and the picture and channel scans were dramatically improved.
