IMPORTANT POINTS
You will need a drill and drill bit, roof-compatible sealant and appropriate
fasteners to install all components and wiring.
The installer is responsible for determining the most appropriate
fasteners to secure the antenna bracket to the roof. Depending on
the roof material, fasteners such as lag screws, well nuts, sheet metal
screws, toggle bolts and T anchors may be used, and should always be
used in combination with a roof-compatible sealant.
The installer is responsible for properly securing the coax cable to the
roof (for example, cable ties and cable tie mounting pads).
heads with roof-compatible sealant.
Do not put sharp bends in coax cables.
This can reduce signal strength from the antenna.
overlap, a condition called oscillation occurs. Oscillation can be thought of as
noise, which causes the booster to shut down to prevent damage. The best
way to keep these spheres of signal from overlapping is to maximize separation
between the booster and the antenna.
IMPORTANT! The aluminum casing of your signal booster will adjust to the
temperature of its environment, but is designed to protect the signal booster
technology. For example, in the summer, the signal booster case may be
as hot as 150 degrees inside your vehicle. These high temperatures will not
be sure to place your signal booster in a location with adequate ventilation
and away from direct sunlight or moisture.
The signal booster may remain on in vehicles whose 12V DC power sources
do not automatically shut down when the vehicle is turned off. This could
result in discharging the vehicle’s battery in one to two days.

(Route the cable through an open door or window for the
soft install.)

INSTALLATION
1. Fasten the outside antenna to the mounting bracket with the supplied
screws and washers (see page 5).
2. Connect the separate 20’ cable to the antenna (LARGE CONNECTOR).

4. Fasten bracket to roof. Make sure fastener holes and fastener heads are
properly sealed.

5. Route the cable to where it will enter the vehicle.
IMPORTANT! Make sure to avoid any cabling, pipes, etc. that may be
damaged by drilling.
6. Drill an appropriately sized hole and feed the cable into the vehicle.
7. Seal the roof hole so it is completely waterproof (inside and outside).
8. Inside, place booster in desired location or install the booster to wall.
Connect cable to booster.
9. Connect inside antenna cable to booster and place inside antenna in
position.
10. Plug booster into power source.
If using the included booster
mounting bracket, remove
the booster from the bracket.
TIP
Fasten bracket to wall, then
snap booster back into bracket.

SIGNAL BOOSTER STATUS LIGHT
SOLID GREEN
This indicates your booster is functioning properly and there are no issues
with installation.
BLINKING RED, THEN SOLID GREEN
This indicates one or more of the booster bands has reduced power due to
a feedback loop condition called oscillation. This is a built-in safety feature
to prevent harmful interference with a nearby cell tower. If you are already
experiencing the desired signal boost, then no further adjustments are
necessary. If you are not experiencing the desired boost in coverage, then
refer to the troubleshooting section on the next page.
SOLID RED
This is due to a feedback loop condition called oscillation. This is a built-in
safety feature that causes a band to shut off to prevent harmful interference
with a nearby cell tower. Refer to the troubleshooting section on the next
page.
LIGHT OFF
If the signal booster light is off, verify your power supply has power.
NOTE: The signal booster can be reset by disconnecting and reconnecting the
power supply.

This section is only applicable if the booster is red or blinking red and you
are not experiencing the desired signal boost.
2. Relocate the inside and outside antenna further away from each other. The
objective is to increase the separation distance between them, so that they
will not create this feedback condition discussed before.
3. Plug power supply back in.
4. Monitor the indicator light on your signal booster. If after a few seconds
3. Increase the separation distance until the condition is corrected and/
or desired coverage area is achieved. NOTE: Horizontal separation of
the two antennas typically requires a shorter separation distance than
perpendicular separation.

Each signal booster is individually tested and factory set to ensure FCC
compliance. The signal booster cannot be adjusted without factory
reprogramming or disabling the hardware. The signal booster will amplify, but not
alter incoming and outgoing signals in order to increase coverage of authorized
will reduce gain until a signal is detected. If a detected signal is too high in a
frequency band, or if the signal booster detects an oscillation, the signal booster
will automatically turn the power off on that band. For a detected oscillation
the signal booster will automatically resume normal operation after a minimum
permanently shut off until the signal booster has been manually restarted by
momentarily removing power from the signal booster. Noise power, gain, and
linearity are maintained by the signal booster’s microprocessor.
The manufacturer’s rated output power of this equipment is for single carrier
operation. For situations when multiple carrier signals are present, the rating
would have to be reduced by 3.5 dB, especially where the output signal is
re-radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device.
This device complies with Part 15 of FCC rules. Operation is subject to two
conditions: (1) This device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may
