Overview: The Channel Master 4228 antenna
is designed for UHF frequencies only, both digital and analog. It can be mounted
on a roof, on a wall, to a chimney, or in an attic.
Nest Brackets: The nest brackets and
U-bolts are used to mount the antenna to a mast. The outer diameter of the mast
should be approximately 1-1/4 inches.
If using a rotor on the antenna mast, make sure a 20" 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 included transformer is
connected to the antenna tap-off points using the included wing nuts. The other
end of the transformer has a female F-type connector. The included waterproof
rubber weather boot should be installed over the cable connection to guard
against corrosion. Note: Coax cable is not provided, RG-6 is recommended.
The rated range of the 4228 is 60 miles, but the distance is approximate, actual
performance depends on too many variables to predict accurately
The average gain across the UHF frequency range is 12dB.
