SIGNAL BOOSTER – This amplifier will enhance and strengthen the signal received by your indoor/outdoor non-amplified passive TV antenna. Amplifiers will clear up any low-strength fuzzy or pixelated channels – in some cases the number of channels you receive may change depending on your distance from the local broadcast towers. | 4-WAY SPLITTER – Works with all brands of TVs and passive antennas to distribute one audio/video source to up to four devices with F-type coaxial connectors. This will require coaxial cable (sold separately). | EASY INSTALLATION – Simple to set up and comes with an AC power adapter user manual and installation instructions. | IMPORTANT NOTE – Using an amplifier does not guarantee that you will receive more TV channels but it will strengthen the signal of available channels in your area. The number of channels and the reception quality you receive will vary based on distance from broadcast towers antenna position and obstacles including hills buildings and trees. | SATISFACTION GUARANTEED – GE is America’s #1 antenna brand and is backed by a limited-lifetime warranty and free U.S.-based technical support should you have any questions or issues with your purchase.
