Pre-Installation Check and Calibration
The Hy-Gain AR-40 antenna rotator is designed
to support and rotate large TV antennas, small CB
base antennas, and small Amateur antennas. The
AR-40 is rated to rotate antennas with up to 1.5
sq. ft. of wind area when mast mounted or 3.0 sq.
ft. when mounted inside a tower.
The AR-40 rotator unit must be wired to the con-
trol unit with a 5-wire cable. Number 22 gauge 5
conductor cable will allow normal operation for
cable lengths of up to 75 feet (22.86 m). For
longer runs, use a heavier gauge wire.
The control unit must be placed inside the house
or other protected location. The maximum voltage
produced by the control unit is 18 VAC.
Before mounting the rotator unit on your mast or
tower, check the operation with the control unit
and cable. Strip all conductors at both ends of the
cable and attach to the terminals. Connect
terminal 1 to terminal 1, etc. On the control box,
simply insert the bare wire between the nut and
the terminal and tighten the screw. Do not wrap
the wire around the screw!
Plug the control unit line cord into a convenient
wall outlet. Turn the direction control knob to
"N". Momentarily press down on the start button.
The rotator will start to turn and the indicator light
will come on. When the rotator reaches "N", it
will automatically stop and the light will go off.
