The Mohu Leaf 50 (formerly Leaf Ultimate) is the amplified version of the world?s first paper-thin HDTV antenna. This omni-directional antenna reaches out in a 50-mile radius from your home to bring you the most popular over-the-air (OTA) TV shows, news and sports, on both network and local television in full 1080 HD - for FREE. No need for cable or satellite fees to watch stations like PBS, ABC, CBS, NBC and Fox, with each network having its own digital sub-channels for maximum content. The Leaf 50 is derived from advanced U. S. Military technology and is combined with Mohu?s CleanPeakTM filter technology to eliminate unwanted cellular or FM signals.
