Jrifedptry HDTV Aerial Amplifier Signal Booster TV HDTV Antenna with USB Power Supply Kits

This amplifier can make your TV antenna channels, improve the clarity of the frequency, expand the receiving range. Channel reception is dependent upon distance from broadcast towers, terrain, surroundings, and weather. Check out what channels are available in your area first and how many you are to receive. The number of channels you can receive is determined by what's being broadcast in your area. 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. 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.
