This amplifier can make your TV antenna receive more channels, improve frequency clarity, expand reception range. 2. The number of channels you can receive is determined by what is broadcast in your area. 3. Channel reception depends on distance from broadcast towers, terrain, environment and weather conditions. 4. First check which channels are available in your area and how many you can receive. 5. If your TV picture is not crystal clear or you cannot receive weak signals from distant towers, use this amplifier to boost weakened signals. 6. 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 being received.
