If you want reliable over-the-air TV reception, but can't install a large rooftop antenna, check out Terk's FDTVO. This compact antenna pulls in standard and high-definition digital broadcasts, and includes an amplifier to improve the reception of weaker signals. And with its multi-directional design, you don't need to worry about pointing the FDTVO in a specific direction to get a clear picture.
You can install the FDTVO either outside or in your attic. It includes a mounting base, arm, and the necessary hardware. If you prefer, you can also mount it to an optional mast.
