Section 1--Introduction
1. INTRODUCTION
The Kustom Signals’ Eagle® II series radar units come from
a long-standing commitment to the law enforcement
community to provide quality, state-of-the-art speed
measuring equipment. The Eagle® II series radar units
incorporate features that have never been available on
moving radar before.
Directional Golden Eagle® II units use Digital Signal
Processing (DSP), which allows Kustom Signals designers
the opportunity to add features such as same direction,
fastest vehicle, TruTrak, and the newest directional features
that distinguish approaching and receding vehicles. With
these features, the officer can better identify the offending
vehicle and eliminate much of the confusion of high traffic
environments.
All of these features and performance standards are packed
into a small, lightweight unit, providing the most flexibility
for the operator.

Section 3—Inspection & Mounting
3.2 EQUIPMENT MOUNTING
3.2.1 AUXILIARY POWER RECEPTACLE
Cigarette lighter receptacles have been the traditional source
of power for traffic radar over the years. In the newer
vehicles, it is possible that poor grounding of this receptacle,
electrical noise from the vehicle's alternator charging
system, electrical fuel pump and microprocessor noise can
combine to create an unacceptably high level of ambient
electronic interference.
This interference can affect the radar's performance in
several ways: decreased range, no target speeds being
displayed or abnormal tones or noise in the audio.
Available for each Directional Golden Eagle II radar system
is an auxiliary power receptacle, which mounts under the
dashboard and wires directly to the battery.
1. Mount the receptacle in the desired location using the
hardware provided.
2. Connect the black wire to the receptacle's mounting
bracket. Connect the white wire (with Faston terminal)
to the rear plug of the receptacle. Route the cable
through the firewall and up to the battery.
3. Connect the white wire of the power cable to the battery
(+) positive terminal and the black wire to the
(-) negative terminal.
4. The Auxiliary power receptacle is supplied with a 2 amp
fuse to protect the battery should the cable become
shorted.

3.2.2 INDICATOR UNIT
CAUTION: Equipment mounted in 1994 and later series
police vehicles may interfere with the operation of
passenger side airbags. Please refer to the vehicle
manufacturer or your Kustom Signals District Manager for
additional information on safe mounting areas within the
vehicle.
1. The indicator unit consists of two components: the front
display panel, which contains the unit's displays and
switches, and the logic unit, which contains the main
circuit board. These two components can be mounted in
the vehicle as one piece or they can be separated and
mounted in different locations.
The Directional Golden Eagle II's display panel can be
located overhead, on the dashboard or on the radio rack.
The logic unit can be located under the dash, in the
glove box or under the front seat.
2. Locate mounting bail. Position the indicator for best
viewing position in the patrol vehicle and mark the
location for the mounting screws.
3. Drill a small pilot hole at the marked locations.
4. Set the bail bracket in place and secure to the dashboard
or other mounting location with mounting screws.
5. If the logic section is separated from the display,
consider mounting it in a convenient yet protected
location, i.e. under the dash, in the glove box or under
the front seat. The interconnect cable for the two
components attaches to the rear of the display panel and
front of the logic unit.
3.3
Section 3—Inspection & Mounting
3.2.3 FRONT ANTENNA MOUNTING
Provided with the Directional Golden Eagle II is a
windshield mount for the antenna. Contact your District
Manager or Kustom Signals' Customer Service department
for other optional antenna mounts.
NOTE: Mounting of the antenna bracket to the dashboard
or any metal bracket (such as the radio rack) may
cause improper grounding of the antenna. This
would be noticed by reduced range and/or a high
pitched squeal in the audio. Use of the Kustom
Signals' isolation kit, P/N 050-0200-00 will
eliminate improper grounding.
1. Attach the antenna to the mount.
2. Connect the antenna to the Directional Golden Eagle II's
logic unit, front antenna port. Refer to Sec. 4.1 for
antenna port location.
3. Connect the Directional Golden Eagle II's power
connector to the proper power source. See Sec. 3.2.1.
4. Momentarily depress the POWER switch on the front
panel of the Directional Golden Eagle II (refer to Sec.
4.0 for location and function of front panel switches). It
will process through a lamp test and internal test as
described later in Sec. 6. Select Stationary mode ALL
by depressing the remote MODE switch until ALL is
displayed in the Patrol window. Both directional
indicators (front antenna) will be lit.

Section 3—Inspection & Mounting
5. Momentarily depress the AUDIO then the PAT-SET
switch. This places the Directional Golden Eagle II in
the unsquelched (audio on) mode. If necessary, depress
the AUDIO switch then the RANGE (up) switch to
increase the audio level.
6. Start the patrol vehicle and position the A/C - heater fan
to a mid-range speed. Move the antenna/mounting
bracket to different positions on the windshield while
listening to the audio. If there is fan interference, the
audio will have a raspy sound instead of just noise.
Position the antenna to minimize the amount of fan
interference. Mark this position on the outside of the
windshield, using a grease pencil.
7. After the optimum antenna position has been found, glue
the bracket to the windshield using the adhesive
provided.
8. Position of the antenna:
Stationary: Maximum performance of the
system will be achieved when
the antenna is pointed directly
toward the vehicles being
monitored.
Moving: Aim the antenna parallel to
the ground and straight down
the roadway.
3.5
Section 3—Inspection & Mounting
3.2.4 REAR ANTENNA MOUNTING
1. Place the antenna on the rear-mounting bracket.
2. Follow the procedure for determining any fan
interference per Sec. 3.2.3, steps 4-6. Set the
Directional Golden Eagle II for stationary mode ALL,
rear antenna.
Stationary Mode
Rear Antenna
3. After the optimum position has been located (and marked
per Sec. 3.2.3 Step 6), permanently attach the mount to
the rear window using the adhesive provided.
4. Position the antenna cable behind the rear seat and under
the rear floorboard, then route up to the logic unit and
connect. This method of mounting will minimize the
antenna from moving around in the vehicle should it
break loose in an accident. It should also prevent
anyone from using the cable as a weapon against the
officer.
5. Position the antenna parallel to the ground and straight
down the roadway.
3.2.5 SPEEDOMETER PULSE CABLE
INSTALLATION
1. The speedometer pulse cable has a two-conductor plug
at one end and no plug at the other end. The plug
connects into the “SPDOMTR” connector on the rear
panel of the Directional Golden Eagle II.

Section 5—General Theory of Operation
5. GENERAL THEORY OF OPERATION
5.0 GENERAL
The Directional Golden Eagle II moving radar system
transmits a Ka-Band radio frequency in compliance with the
Federal Communications Commission (FCC) regulations.
A portion of the transmitted signal strikes the surface of the
roadway and surrounding terrain and reflects back to the
antenna. The returning signal is the "groundspeed"
Doppler. From the antenna, it travels to the Digital Signal
Processing (DSP) where the signal is translated to the speed
of the patrol vehicle (groundspeed) and is displayed in the
PATROL display.
The Eagle II series has an exclusive feature from Kustom
Signals using the patrol vehicle’s speed sensor pulses,
which steers the DSP processor to look for the
“groundspeed” Doppler signal in a specific speed range.
This feature will eliminate the often-annoying anomalies
such as shadowing, combined patrol speeds, splitting
speeds, and displaying speeds in the PATROL window
when stopped at a traffic light or sign.
In moving opposite direction mode, a portion of the
transmitted signal strikes an oncoming vehicle (target
vehicle) and returns a Doppler frequency higher than the
groundspeed because the two objects (patrol vehicle and
target vehicle) are converging. This returning signal is the
"target" Doppler. The counting unit measures this speed of
convergence, or combined speed.
Upon receiving the "target" Doppler signal, the counting
unit automatically computes the difference between the
speed of the patrol vehicle and the target vehicle. The speed
of the approaching vehicle registers in the TARGET
display. If, for example, a patrol vehicle is traveling 55
MPH and an approaching vehicle is traveling 65 MPH, the
Directional Golden Eagle II would process the groundspeed
of 55 MPH and the combined speed of 120 MPH. The DSP
would subtract the patrol speed from the combined
5.1
Section 5—General Theory of Operation
speed (120 - 55 = 65). The PATROL display would
indicate 55 and the TARGET display would indicate 65.
In the Moving Same Direction mode of operation, the target
Doppler is received from a target traveling in the same
direction as the patrol vehicle. These "groundspeed"
Doppler and the "difference" Doppler signals are received
and sent to the DSP. The Difference Doppler is the speed
difference between the patrol vehicle and a vehicle traveling
in the same direction. The Directional Golden Eagle II uses
its directional determination capabilities to automatically
determine if the target vehicle is traveling faster or slower
than the patrol vehicle. The unit will display the patrol
speed then automatically add or subtract the "difference"
speed to the patrol speed for the target speed.
If the patrol vehicle's speed was 55 mph and a target was
traveling in the same direction at 70 mph, the Directional
Golden Eagle II would display 55 in the PATROL display
then add the "difference” Doppler signal 15 to the PATROL
display (55 + 15 = 70) and display 70 in the TARGET
window.

Section 5—General Theory of Operation
5.1 MICROWAVE RF EMISSIONS
Traffic radar operators may have some questions about the
biological effects of exposure to the microwave energy
produced by the radar devices. According to all credible
evidence, the emission levels resulting from traffic radar use
pose no threat whatsoever, either to the radar operator or to
target vehicle occupants.
One widely recognized authority for safe limits of
nonionizing radiation exposure is the American National
Standards Institute, which recommends maximum exposure
levels for the frequencies on which Kustom traffic radar
systems operate (ANSI/IEEE C95.1-1999, "Standard for
Safety Levels With Respect to Human Exposure to Radio
Frequency Electromagnetic Fields, 3 kHz to 300 GHz").
These exposure levels, expressed in terms of power density,
are 7 mW/cm2 for X-band radar units, and 10 mW/cm2 for
K-band and Ka-band radar units. Similarly, the
Occupational Safety and Health Administration (OSHA), a
division of the U.S. Department of Labor, recommends a 10
mW/cm2 exposure limit for all three frequency bands
("Radiation Protection Guide", 29 CFR, Chapter XVII,
Subpart G, Part 1910.97). This limit is clearly accepted by
most reputable scientific and medical authorities.
Kustom radar systems utilize microwave transmitters which
produce aperture power densities, measured directly at the
face of the antenna, in the range of approximately 0.3 to 2.3
mW/cm2. Typical levels for the vast majority of units are in
the 0.4 to 1.0 mW/cm2 range, which is but a small fraction
of the recognized safe limits. Bear in mind that these are
level measurements taken directly in the main beam of the
antenna, and that the power densities produced at the sides
and rear of the unit are typically at least one hundred times
lower than in the main beam.
5.3
Section 5—General Theory of Operation
Another reference document on this topic is a DOT
publication entitled "Field Strength Measurements of Speed
Measuring Radar Units" (NHTSA Technical Report #DOTHS-805 928). This report documents a series of tests
performed by the National Bureau of Standards on twentytwo commonly used models of traffic radar units, from six
different manufacturers including Kustom. Aperture power
density levels measured were from 0.25 to 2.82 mW/cm2,
while back-lobe power density values ranged from 0.001 to
0.02 mW/cm2. These measurements were obtained with the
radars mounted inside vehicles, as in normal operating
conditions. Since the NBS study, other laboratories have
duplicated these types of measurements, producing
consistently similar results.
For a free copy of the latest information regarding the safe
human exposure standards, please call or write Kustom to
request the "RF Emissions Packet." You may contact us at

While traffic radar devices do emit microwave energy, the
levels are so low that there are no probable harmful effects.
You may use your Kustom radar unit with complete
confidence in its safety, as well as in its accuracy.

Section 6—Testing Procedures
6. TESTING PROCEDURES
6.0 GENERAL
The internal test and tuning fork tests explained below
should be conducted at the beginning and end of each patrol
shift to ensure the accuracy and functionality of the unit.
The results of these tests may be recorded in a radar log,
similar to the log found at the end of this manual.
6.1 POWER ON
Momentarily depress the POWER switch. The unit will
display all LED display segments (888) and turn on all
lamps and indicators on the front panel. After
approximately 1 second, the unit will perform several
internal circuitry tests and a crystal cross check to verify the
accuracy of the speed processing circuitry.
If these pass successfully, the unit will display "PAS" in the
TARGET display (stationary operation) or both the
TARGET and PATROL displays if the unit is in the moving
mode of operation. This will remain for approximately 1
second. The current audio level will then be displayed,
indicated by "Aud" in the TARGET window and the
PATROL window will display the audio volume level
selected (0 - 9). The audio will be un-squelched during this
state, so the volume level can be heard in the speaker.
One second later, "rnG" will be displayed in the TARGET
window and the PATROL window will display the current
range level (0 - 6). (The higher the range setting, the more
sensitive the target captures.) After another second, the
displays will clear and the unit will be operational in the
same mode that it was in when the unit was shut off.
