We went camping this weekend for the first time and can't figure out how to get the TV to work. We were at a state park so we were relying on the antenna for reception. Plug underneath the TV was plugged to 'cable' outlet. Other option underneath was 'satellite'. I could get one channel very fuzzy but no sound. FIL 20 year old trailer had much better reception with rabbit ears in the same park. Salesman said it should be set up from factory to work. Any ideas? Our next outing will be at Branson. Earlier we were the only Big Country signed up for the rally, so we won't be hard to find it you have a solution. Thanks!
