The Ultra-Hi Crossfire 100 is a directional (log periodic), line-of-sight outdoor antenna that receives high definition and digital signals from a single direction. This antenna has a reception range of up to 100 miles.

The Channel Master CM-3671 Ultra-Hi Crossfire was designed to be the best performing long-range outdoor TV antenna on the market. It offers reliable reception and superior gain across the entire bandwidth including Low VHF, High VHF, UHF and FM signals. With a range of 100+ miles, the Ultra-Hi Crossfire Antenna is perfectly optimized for use in rural and weak signal areas. Thanks to a rugged double boom design and high-strength bracing, the antenna's elements are kept in position, sagging and structural distortion is prevented even under heavy ice loads and high winds.
