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.
