INSTALLATION OF LASER/RADAR ANTENNA
General Information
The laser/radar antenna is waterproof and designed to be
mounted at the front of your vehicle. Optimum mounting
location is near the license plate area. Since this module also
includes a Laser receiver, the front of this module needs to
“look” down the road with no obstructions. Radar signals will
pass through non-metallic materials such as fiberglass and
plastic, however, because of the laser receiver, there can be
no material blocking the receiver’s antenna window. If
obstruction cannot be avoided, consider the vertical mounting
option. Because the optimal location for mounting the antenna
varies by vehicle type, the hardware supplied is designed to
offer a wide variety of mounting options. We suggest choosing
the option that enables the antenna to be securely fastened and
provides the antenna window adequate forward visibility.
NOTE: The “antenna window” is the bubble area on the case
All references to antenna in this manual will be the bubble
area.
NOTE: Use of hardware that is not supplied or DRILLING
into the case will cause damage to the receiver and void the
warranty.
TIP: Use removable thread lock on the hardware to prevent any
bolts from backing out due to vibrations.
Antenna Mounting Brackets
There are two types of mounting brackets for the antenna:
Large L (1) and Small L (2). The Large L bracket fastens to 2 – 4
holes on the cover of the antenna. The Large L Bracket may be
fastened to the antenna in a variety of positions.
Do not drill into the receiver housing!

INSTALLATION OF LASER/RADAR ANTENNA
The layout of the holes on the large L bracket accommodates
multiple antenna mounting positions.
This arrangement provides flexibility for fastening the antenna/
bracket assembly to your vehicle in a manner that allows the
antenna window (ANTENNA) to have a forward looking view of
the road ahead. The Small L Brackets (2) may also be fastened to
the antenna in different positions as shown below:
The small L brackets may be fastened to any of the four holes on
the antenna.
Use one M3 x 20 bolt, washer and nut to fasten each Small L
Bracket to the antenna. Again, do not over tighten the screws.
In some situations it may be advantageous to use both the
Large L and Small L Brackets to install the antenna in a vehicle.
TIP: Use removable thread lock on the hardware to prevent
any bolts from backing out due to vibrations.

INSTALLATION OF LASER/RADAR ANTENNA
Large L and small L brackets maybe used in combination in a
variety of differnet ways.
The Small L Brackets are fastened to the Large L Bracket using the
#10-32 x 1/2" bolts, #10-32 nuts and lock washers.
To fasten the Large L or Small L Brackets to your vehicle, mark the
supporting structure through the appropriate holes in the brackets,
and then drill the holes in the supporting structure with a 13/64"
drill bit. Attach the bracket(s) to the supporting structure using two
bolts (#10-32 x 1-1/4") and corresponding nuts, flat washers, and
lock washers. Because rough road surfaces can cause excessive
vibration or bouncing, be certain to fasten the bracket(s) securely to
your vehicle.
Horizontal or Vertical Mounting Of Antenna
The antenna can be attached to the vehicle in a horizontal or
vertical position, or at any angle in between. Select the position
that allows you to fasten the antenna to your vehicle in the most
secure manner.
Horizontal Mounting - antenna window facing down the road
When mounting the antenna in a horizontal position (or on an
angle), remember to keep the ANTENNA window as close to
perpendicular as possible to the road surface
