We got tired of screwing the TV cable into the RV outside RV connection and the campground connection. For a few bucks you can purchase screw in connectors to each end of your TV cable . This makes it possible to slide each end into of your TV cable into the RV & campground TV hookup. The adapters are available at Radio Shack & some Hardware stores.
