I have a wingard hd8200u, with a preamp ap8275. I live on Long Island on a hill at an elevation of 300' with the antenna 30' above the ground. Its 501 miles form the empire state building where the major networks emit from. I can barely get any signals from the set up with the preamp unplugged and none with it on. I thought the preamp was bad, so I purchased a channel master cm7777, with the same results. I try both with the FM trap on and off. I am surrounded by a few 50' broadcast antenna's. Do i have too much FM noise to use a preamp? I need help to improve my reception. Thanks!
