Installing and Programming
the Indoor Control Unit
Step 1: Set up to the control unit
1. Determine the length of cable needed to run between
the outdoor and indoor units. Cut the cable to that
length.
2. Strip about 1/2” of the jacket off the end of each wire.
3. Insert each bare wire into the connector plate on the
control unit’s back panel as shown below.
4. Release jacket to secure on connector.
IMPORTANT: The unit must be wired correctly.
Damage can result from improper wiring.
5. Plug power cord of the control unit into AC outlet.
6. Turn on the unit.
The CHANNEL on the front panel reads
0, and the
ANT POSITION display reads 00.

2 wire #2 to #2
1 wire #1 to #1
5. Lower the antenna mast between the brackets and
the rotor. Tighten the nuts. Moderate tightening with
a 7/16” wrench will cause the teeth to grip the mast
securely.
6. After connecting the antenna lead-in cable to the
antenna, fasten it to the antenna mast using stand-off
insulators (not included) as shown. Provide a generous
loop at the drive unit.
7. Attach the lead-in cable to the support mast with
stand-off insulators (not included) approximately
every four feet.
8. Tape the rotator control cable directly to the support
mast.
Step 3: Install the antenna/cable
1. Insert the 2 U-bolts through the back of the rotor
section of the drive unit.
2. Place the remaining 2 brackets over the ends of the
U-bolts.
3. Put the nuts with attached lock washers on the very
end of the U-bolts to keep the brackets in place.
4. Position the brackets and nuts/washers so that they
leave just enough room for the antenna mast to go
through.
Note: Use no more than 3” of antenna mast between the
rotor and the antenna itself.

IMPORTANT: Do not overtighten to the point that you
deform the mast, since this will reduce its strength. Mast
diameters of 1.25” to 2” (3-5cm) may be used. The 1.5”
(3.8cm) size or larger is recommended for unguyed masts
over 6’ long, or where large antennas are used. If guy
wires are used, fasten two through each of the two holes of
the lower bracket.
