About the Channel Master 4221HD
Channel Master's model 4221HD antenna can receive digital and analog over-the-air TV signals in the UHF band only (most digital TV signals are in the UHF band). The 4221HD is optimized for distant "near-fringe" reception of HDTV. Its space-efficient design is suitable for roof and attic installations. For years, I've been getting great results with a 4221HD installed in my attic.
The 4221HD is classified as a Medium-sized Directional antenna. For tips on selecting an antenna, and links to websites that help you locate HDTV signals in your area, check out our article explaining choosing the best HDTV antenna.

More details on the Channel Master 4221HD
Overview: The Channel Master 4221HD antenna is designed for UHF frequencies only (channels 14-69), both digital and analog. It can be mounted on a roof, on a wall, to a chimney, or in an attic.
Mounting Brackets: The mounting brackets and the U-bolt are used to mount the antenna to a mast. The outer diameter of the mast should be approximately 1-1/4 inches.
Turning Radius: If using a rotor on the antenna mast, make sure a 12-1/4" turning radius around the antenna is clear of obstruction.
Grounding: The antenna and mast should be properly grounded. Grounding provides lightning protection for the antenna and your TV set.
Note: No grounding hardware is provided with the antenna.
Connections: The balun is built-in (attached at the factory) and has a female F-type connector. The included waterproof rubber weather boot should be installed over the cable connection to guard against corrosion. A twist-on threaded F-connector is also included.
Note: Coax cable is not provided, RG-6 is recommended.
Operating Range: The rated range of the 4221HD is 45 miles, but the distance is approximate, actual performance depends on too many variables to predict accurately.
Gain: The average gain across the UHF frequency range is 11.5 dB.
