When considering an indoor antenna here's my advice. I've tested a lot of indoor amplified and non amplified antennas and the Flatwave FL5500A is the best indoor antenna we've tested so far. In most cases the distance to the TV transmitters to the receiving antenna (your location) should be within 35 miles or less (The manufacturer does state up to 50 miles). Also, consider the building material used to construct your home. Brick, metal, masonry and foil are the worst materials for TV reception. If the signals must penetrate any of these materials you may have to place the Flatwave antenna in a window or in a location where the signals don't have to penetrate the obstructing material. The Flatwave antenna comes with 18'.5' of connection cable and peal and stick adhesive so it can easily be secured to the window, wall etc... A window facing the TV transmitters is best but not usually necessary. Before purchasing the Flatwave or any indoor antenna understand that indoor antennas will not perform as good as outdoor antennas and the possibility exist that an outdoor antenna may be required at your location. If your location meets the criteria for indoor TV reception the Winegard amplified FlatWave FL5500A indoor antenna is the way to go. When compared to the non amplified FlatWave FL4000 we found in most cases the built-in low noise preamplifier of the amplified Flatwave FL550A noticeably improved reception over the non amplified version. The Flatwave is covered by our 90 day money back guarantee.
