When hooked up to park cable at two separate parks, we have poor pictures on our lower channels and a few of the upper ones. At first I thought it was a problem with the parks cable, but when the problem followed me to the next park, I knew it was something in the coach. To add to the mystery, with no change to any thing it cleared up for a while and then went back to snow like reception. I changed the coax from the splitter to the TV, but no change. The TV in the bedroom doesn't seem to be affected with the snow!
Any ideas on what to check next would be greatly appreciated. I currently have a "stock" set up, but was planning on adding some type of switch when using satellite.
