I live on the Cumberland Plateau in Middle Tennessee (Crossville). Some 1800 feet above sea level. I have a UHF/VHF antenna on a 40 foot tower. I recieve Nashville analog fairly good using some sort of booster. Although I never really watch it anymore. It appears to me that Im about 90 miles (as the crow flies) from the HDTV towers. Am I to far away to get HiDef out of Nashville?
