About the Channel Master 4228HD
Channel Master's 4228HD antenna can receive digital and analog over-the-air TV signals in the UHF band and high VHF band (nearly all digital TV signals are in the UHF or high-VHF bands). The 4228HD is optimized for "deep-fringe" reception of HDTV — it's one of the highest-gain antennas available.
This antenna features a highly directional design that will provide best results when most or all of the desired stations are transmitting from the same location. For clearer reception, pair the 4228HD with the 7777 preamplifier — several Crutchfield employees are receiving digital stations from 50+ miles away with a similar setup. Also, if you'd like to pull in signals from different areas, consider a rotor to aim your antenna in the right direction.
The 4228HD is classified as a Large Directional antenna. Its space-efficient design is suitable for roof and attic installations (mast recommended).

More details on the Channel Master 4228HD
Overview: The Channel Master 4228HD antenna is designed for over-the-air broadcasts of UHF frequencies and high-band VHF frequencies (channels 7-13 and 14-69), both digital (HDTV) and analog. It can be mounted on a roof, on a wall, to a chimney, or in an attic. The antenna can be used with digital converter boxes or HDTV ready televisions.
Note: Many digital broadcasts still include non-HD content.
Construction: The Channel Master 4228HD antenna features a long lasting durable design with heavy duty aluminum elements and UV stabilized plastics.
Mounting Brackets: The mounting brackets and the U-bolt are used to mount the antenna to a traditional antenna mast (sold separately). 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 20.5" 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 4228HD is up to 45 miles (channels 7-13) and up to 60 miles (channels 14-69), 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 12dB.
