Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
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
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
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
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.
