Before installing the rotator, mast, and antenna, prepare the rotator control cable and test rotator system performance on
the ground . Potential alignment, cabling, or other problems can quickly be resolved on the ground; once a rotator is
mounted, however, troubleshooting may require that the tower be climbed and/or the rotator be removed and lowered to
the ground!

Control Cable Installation
In this Rotator, the user must supply and prepare the
control cable, per the simple instructions below.
The control cable to be used should have six stranded
conductors of at least 0.5 mm (#20 AWG) diameter if
the cable is shorter than 40 m in length (125’); if the
cable is longer than 40 m, use conductors with a diam-
eter of 0.75 mm (#18 AWG) or larger.
1.
Disassemble the supplied round plug: slide off the
rubber boot, remove the setscrew from the shell us-
ing a small screwdriver, then unscrew the shell from
the plug. Save the setscrew in a safe place until step
10, so you don’t lose it.
2. Slide the rubber boot and the round shell over the
“rotator” end of the cable. Leave enough cable pro-
truding to allow easy dressing the end of the cable.
3. Using special care to avoid nicking the insulation of
the individual wires, strip back 15 mm (about 5/8”)
of the outer jacket of the cable from both ends. Now
strip 5 mm (about 3/16”) of insulation from each
wire, being careful not to nick the conductors.
4. Solder the wires to the round plug pins, noting the
color of the wire and the number associated with
each pin for reference later.
Pin 7 of the round con-
nector is not used! Confirm that all solder joints are
firm and cleanly made, as this part of the cable will
be difficult to access once the rotator is installed on
top of the tower. Do not slide the shell onto the con-
nector at this time.
5. Crimp the supplied pin contacts onto the wires on
the opposite end of the cable, per the illustration
below.
6. Referring to your notes of the wire color at each pin
of the round (rotator end) connector, insert the pins
into the rectangular plug at the opposite (controller)
end of the cable. Be sure that each wire from the
round connector is routed to the corresponding pin
number in the rectangular connector (i.e. 1 to 1, 2 to
2, etc.).
7. Temporarily connect the round plug to the rotator,
and the rectangular plug to the controller. Make sure
that the
POWER switch on the controller is set to
“OFF,” then plug the controller’s AC cable into your
station’s AC outlet.
8. Set the controller’s
POWER
switch to “ON.” Verify
that the controller’s pilot lights have become illumi-
nated.
9. Press the LEFT (rotation) side of the seesaw switch,
and confirm that the rotator (when viewed from the
top) and the controller’s needle turn counter-clock-
wise together. Stop rotation, then press the
RIGHT
(rotation) side of the seesaw switch, and confirm that
the rotator and indicator needle turn clockwise. If
rotation does not occur as indicated, turn the
POWER
switch “OFF,” and re-check your cable
connections.
10. If the rotator and controller are working as described,
replace the plug shells, setscrew, and rubber boot
(removed in step 1).
