We just bought our first living quarters horse trailer and it came with an RS-1500 antenna. We bought a 23" HD flat screen TV and used coax cable to hook up the TV to the antenna and everything on the TV is fuzzy. Are we doing something wrong? We don't have an option to even change channels on the TV. Any advice would be great! We are leaving for a big horse show Friday early morning and I need to know what we can do.
