Installing the Outdoor Drive
Unit
Step 1: Attach cable to the drive unit
1. Run cable (not included) to the drive unit.
IMPORTANT: Up to 280’ (84m) of 20AWG 3
conductor cable may be used. For longer runs, use heavier
gauge wire.
2. Unscrew the single screw on the bottom door. Swing
the door open.
3. Remove the grommet and insert the cable thru the
slot. Press the grommet back into the housing.
4. Separate leads for 1.5”(4cm) and strip off the
insulation for 0.5”.

Step 2: Mount the drive unit
If you’re not mounting the unit inside a tower, you’ll
need to mount it to a separate mast (not included). This
kit comes with the necessary hardware for mounting.
CAUTION: Select a mounting location where the
antenna cannot come in contact with power lines while it
is being installed, and where the installation will not fall
across power lines if a guy wire should fail.
1. Screw the 4 threaded inserts in the four holes in the
side of the drive unit base. One end of each insert
has a slot you will use with a flat-head screwdriver
to make sure the inserts are in as far as they will go.
Make sure you put the opposite end in the drive unit.
Then screw the inserts as far as they will go into the
drive unit.
2. Screw the washerless nuts onto the inserts until they
are snug against the drive unit.
3. Put the largest of the four brackets onto the ends of
the bottom two inserts. Put the nuts with attached
lock washers on the very end of the inserts to keep the
bracket in place.
4. Put one of the other brackets onto the ends of the top
two inserts. Put the nuts with attached lock washers
on the very end of the inserts to keep the bracket in
place.
5. Position the brackets and nuts/washers so that they
leave just enough room for the support mast to go
through.
6. Lower the drive unit onto the support mast until it
stops on the mast nose of the drive housing. Tighten
the nuts. Moderate tightening with a 7/16” wrench
will cause the teeth to grip the mast securely.
5. Find the silver- or wide-jacketed lead and connect it
to terminal 1. Connect the adjacent lead to terminal
2. Connect the third lead to terminal 3. If 4 wire
cable is used, connect both wire 3 and 4 to Terminal
3.
IMPORTANT: Make sure there are no loose strands
which can short between terminals.
6. Doublecheck the wiring order. Close the door and
screw it back into place.
