Digital HDTV Aerial Amplifier Signal Booster TV Antenna Signal Booster Features: Check out what channels are available in your area first and how many you are able to receive. If your TV picture is not crystal clear, or you cannot receive the weak signals from far away towers, use this amplifier to boost the weakened signals. Works with any non-amplified TV fox antennas. We do not recommend using this amplifier if your house is very close to the broadcast tower and the signal is already very strong. The amplifier may cause self-oscillations and result in fewer signals received. Descriptions: This amplifier can make your TV antenna get more channels, improve the clarity of the frequency, expand the receiving range. The number of channels you can receive is determined by what's being broadcast in your area. Channel reception is dependent upon distance from broadcast towers, terrain, surroundings, and weather.
