I just bought a new North Trail 24RBS with a touch screen am/fm/wb radio cd/dvd player. I can't pick up any radio stations and the guy at Heartland says there is a wire antenna behind the player but, regardless, it just doesn't pick anything up. I live 2 miles from a radio station that I can't pick up. Has anyone installed a roof top automotive type antenna and if so, is it hard to install. Any tips. Can I tie the radio into the TV antenna? Frustrated. Brand new trailer and can't pick up any radio or weather alerts.
