Overview: The Channel Master 4220MHD antenna
is designed for UHF frequencies only (channels 14-69), both digital and analog.
Mast Mounting: The antenna can be mounted using the included
standard satellite mast; or it can be mounted to a traditional (straight)
antenna mast. The included mast can be mounted on a roof, under an eave, or on a
Mounting Brackets: The antenna mounting brackets and the
U-bolt are used to mount the antenna to a mast. The outer diameter of the mast
should be at least 1-1/4 inches.
Turning Radius: If using a rotor on the antenna mast, make sure
a 12" turning radius around the antenna is clear of obstruction (the 12"
turning radius assumes the antenna is mounted to a straight mast).
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 4220MHD is 30 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 8.2 dB.
