Antenna works, cable doesn't

We don't often have campground sites with cable TV.
Couple of days ago we did and some stations were clear and some had a lot of "snow".
Today we have cable. When I scanned the channels the Contex TV only found 2 of 25 stations. One was very snowy and the other was clear.

I bought a new cable and now the scan finds all the stations but only one is clear. The rest are snowy.
Pulled the plug from the back of the RV, it's good.
Checked the cables to the TV and from the overhead, they are good.
Campground brought a small TV over and connected it to my site and everything was very clear.

Any thoughts?
I'm using the antenna and get 30 very nice stations.

Turn off the antenna booster. The booster MUST be "on", has a small led lit when on, for antenna watching & MUST be "off" for cable or satellite. Every time you move & change inputs you must go to tv set up menu & scan the channels.

I did not turn the booster ON. When traveling it's off.
I even tried turning it on and then off again.
No joy.

Cable box needed?

My TH has an input for satellite and one for cable. If yours does, try the other input.

I don't think cable box is the answer. To expound on Texan's answer, assuming your green light is off and you have the park cable in the proper connection, I'll bet it is in the setup of the TV. When scanning be sure to set the antenna/input to "cable."

Was this a new condition? Has the tv ever worked correctly on cable? You don't list the make or model of the tv so that may help. Some of the tv's provided by the trailer mnf do not a QUAM tuner and will not rec cable without a cable box if the cable provider doesn't convert the signal. If you do a search on this forum you will find many posts on this issue.

Splitter issue?

Sounds like you could have a bad splitter. If you were able to find it/ them - did you make sure all connections were tight? I have an issue with splitters in my Montana and the satellite connection. Until I get motivated to dig in and possibly re-wire the coach to provide direct dedicated coax for satellite (bypassing all splitters) - i will run a direct cable thru a nearby window. The cable connex and antenna feed works fine but my tailgater for Dish does not like splitters.

Did you 'tune' the TV for local stations? Also, you need to set the TV to cable from antenna. I had a brain fade after buying this 5er - then read the instructions

I had the same exact problem last year with my new 2017 175BH. OTA signals were great, but cable and satellite were a no-go. Turns out the outside connector was bad. Took the mounting plate off, popped out the coupler, replaced it with one that was a known good one, and now all is well. Troubleshooting cable issues can be a pain when the issue is a small one like mine was. Good luck.

Just a thought, as we've had this problem. Turn off all your LED lights to see if reception gets better. They are notorious for causing RF Interference. It may only be one of the fixtures.
