The number of channels that can be received depends on the broadcast content in your area. Channel reception depends on the distance from the broadcasting tower, terrain, surrounding environment and weather. First, check the channels available in your area and the channels that can be received. If the TV picture is not clear, or you cannot receive weak signals from distant towers, use this amplifier to boost the weakened signals. If your home is close to the broadcasting tower and the signal is already strong, we recommend that you do not use this amplifier. The amplifier may cause self-oscillation. happy shopping!
