Note: 1.For flatscreen HDTVs, please check the TV's manual to make sure the TV has a built-in tuner for receiving over-the-air broadcast, and make sure this tuner can receive HD signals or else it will not be able to receive and watch HD channels. 2.Retune your TV and/or digital box from time to time to ensure you are receiving all available services. Retuning takes only a few minutes using the remote control. 3.Signal quality determines the picture quality and how many channels you can receive. Once you receive the antenna, hook it up to your TV, and try moving it around your home to find the placement with the best signal. You might be surprised how many HD channels you can receive! 4.Antenna signal strength can vary depending on distance from the tower, terrain, and weather. Reposition the antenna in a different location if needed. It is best for the antenna to be in line of sight with the TV tower(s) and avoid obstructions. Always re-scan for channels after moving the antenna. 5.This is an amplified antenna. If a signal cannot be received when using the external amplifier, remove the amplifier and try again. In some instances the amplifier may cause self-oscillation, which may interfere with signal reception. 6.If your TV has no built-in tuner, you can add an ATSC digital converter box to receive the HD signal.
