MOTOR DRIVE MOUNT
TM Trunk Lid/Hatchback Mount
K9000
LRM Luggage Rack Mount
OPERATING INSTRUCTIONS
The OPERATING INSTRUCTIONS give you
information on handling mount bracket and accessories.
Before use, please read carefully.
SAVE THESE INSTRUCTIONS.
The K9000 mount is designed for lightweight VHF/UHF
mobile antennas that do not require direct RF grounding.
Flexible antennas (NR770H series) are desirable as they reduce
vibration and shock transferred to the K9000. Excessive torque
should be minimized to ensure satisfactory performance of the
K9000.
Recommended Antennas
For best performance, we recommend DIAMOND NR & SG
series antennas under 45” (such as NR73BNMO, NR770HA,
NR770HB, NR770RA, NR770HNMO, NR770HBNMO,
SG7500NMO, and SG7500A and SG-M510). Use the
DIAMOND SO-239 UHF style base connector and cable
assemblies (DIAMOND C101, C211, C213). For NMO style
antennas, use the DIAMOND C101NMO.
Important Safety Instructions
Explanation of Operation
The antenna may be raised or lowered by depressing Control
Switch. The mount motor contains a limit switch which shall
stop the antenna automatically at its end of travel. When the
switch is ON, the green lamp is lit when raising the antenna and
the red lamp is lit when lowering the antenna.
Features
• The mount bracket has a spring-type back torque limiter which
can prevent the antenna from rattling and protect the car and
mount bracket.
• A protective rubber sheet is attached to K9000TM bracket
which reduces possible discolorations or scratching of painted
surfaces.
• The mount bracket is fully adjustable from angles 45–90 degrees. You can choose from 7 levels of adjustment with the control knob (on side of motor drive).
• For simple wiring of motor drive, a cigar plug is included.
Mounting bracket and base fitment assemblies are separate for
easy angle adjustment.
• Vibration during driving may cause loosening of bolts
and screws. Check periodically and fasten if necessary.
“Locktite” compound can be used to secure threads.
• Should the antenna and mount bracket receive a sharp
impact, they could be broken and fall off which could cause
personal injury or damage. Drive carefully and avoid hazardous branches of trees, etc.
• Strong vibration (i.e. vehicles with diesel engines) may
cause excessive stress on the K9000 mount. Install the
antenna far away from the source of vibration.
Caution
To prevent any damage of the mount bracket, pay attention
to the following instructions.
• This mount bracket is designed for 12 volt negative ground
vehicles. Do not use it in a vehicle with incorrect voltage.
• Do not operate the mount bracket if external temperature is
near freezing or below.
• Avoid hitting obstacles during driving. To prevent such a
situation, the mount bracket has a back torque limiter which
has a spring to absorb impact. This back torque limiter will
work in one direction only.
* The mount bracket is designed for use in negative ground
cars. When the mount bracket is used in positive grounded
cars, the lamp will not light. Reverse connection of the power
cord.
Confirm the parts
Confirm all parts in the package. If any part of the mount bracket
is broken or missing, contact RF Parts with the part number.
Options
To install the mount bracket, optional mount hardware and
coaxial cables are needed. Choose the optional parts to match
the installation location.

Explanation of Operation
Warning
* The back torque limiter contained on this mount bracket
can work only when the limit switch is ON in response to
raising an antenna. For this reason, backlash shall be avoided.
The position of installation should not be reversed. Change
the direction of the mount bracket body if you want to lower
the antenna to the reverse direction.
Loosen the set screws on bottom
of mount bracket body. Turn
the mount bracket laterally to adjust
direction of antenna’s “down”
position. If you want to turn more than
50 degrees, detach the mount bracket
and parts, and then adjust.
1. Trunk/Hatchback (K9000TM Mount Bracket)
Installing K9000TM Mount Bracket on Car
• Choose desired mounting location to ensure strength of mount,
best performance of antenna, and proper opening and closing of
trunk/hatchback.
• Slide mounting bracket over lip edge of trunk/hatchback.
Fasten mounting set screws using enclosed metal protection plate
between screws and vehicle. Install antenna. (See recommended
antennas for proper antenna selection.)
• Proper angle adjustment on trunk/hatchback installations:
Loosen mount bolt and turn mount
laterally.
* If proper angle adjustment is not
possible due to contact between the
mount bracket and the car body, move
installation to different location while
maintaining proper raise/lower direction.
2. Roof Rail/Carrier Pipe (K9000LRM Mount Bracket )

• K9000LRM mount bracket can be installed on round and
square pipes or rails.
Dimensions of pipes and roof rails
K9000LRM mount bracket can be installed on various pipes
and roof rails by adjusting fitments as shown. Install antenna.
(See recommended antennas for proper antenna selection.)

Power Cord Wiring
Operating Angle Adjustment
• Attach wires from control box and motor drive mount.
A positive voltage is applied on both power cords. If power cords
are forced unreasonably or pinched, the fuse may blow due to the
short.
• Wire the connector of the control box to the connector of the
mount bracket. Insert cigar plug.
0.8A Fuse
located in cigar
plug
→
* Using fuse greater than 0.5 Amp may cause damage to mount.
• Mount the antenna before making angle adjustment. Turning of
the adjust knob during antenna’s down position may cause damage to the limit switch.
* Operating angle at shipment is set at 45 degrees.
Set antenna to be raised to 90 degrees by operating the control switch.
Loosen the nut (side of antenna
mount) and set antenna for vertical
position.
Adjust knob by using coin in
coingroove.
• Fasten screws after adjusted.
