Commercial FM broadcasts at frequencies 100 times higher than AM and has its own set of reception problems. Our most common complaints about FM reception are multiple stations on one frequency and multipath hissing caused by hills, buildings and even foil-faced insulation. To make a dramatic improvement in these problems you must use a powerful antenna. Unfortunately, a large outdoor antenna is not possible for most people. We strive to offer you the best outdoor and indoor antennas made today.
