The Sky HDTV Attic / Outdoor Antenna is the newest addition to the Mohu family and offers a completely new take on the traditional rooftop or attic mounted antenna. Weighing in at only 3 pounds, the Sky Attic / Outdoor Antenna is a powerful, amplified antenna solution that was developed from research for the United States military. The antenna design is unlike anything that you will find in texts, literature or competitor's products. Similar to the Leaf antenna or Leaf Ultimate, the Sky outdoor antenna is multidirectional and does not have to be constantly readjusted for optimal signal strength. The Sky Attic / Outdoor Antenna is small, powerful, and unique. With the ability to provide uncompressed HD broadcast to multiple televisions in a home with a range of 60 miles, users will not have to settle with a large, bulky or more expensive rooftop-mounted antenna. The Sky's unique design allows it to be easily mounted in an attic where other antennas are simply too large. The Sky Outdoor Antenna features a tightly integrated low noise state-of-the-art digital amplifier to increase the signal range and improve the quality of the HD broadcast signals. The amplifier is powered via a USB port or with the included power cube.
