Inside this Package
How it Works
Your new Wilson amplifier has been carefully engineered to significantly improve the
performance of your cell phone or cellular data card in mobile applications. Together with
an outside antenna (sold separately), the amplifier’s state-of-the-art technology is designed
to increase your signal up to 10 times, reduce disconnects and dropouts, and increase data
communication rates needed for 3G technologies.
The outside antenna will collect the cell tower signal and send it through the cable to the
amplifier. The signal is then boosted and sent through the inside antenna. Your cell phone
or data card then communicates with the improved signal. When the cell phone or data
card transmits, the signal goes through the inside antenna, is boosted by the amplifier and
broadcast back to the cell tower through the outside antenna.
Wilson Electronics manufactures a wide variety of antennas to help you customize your
amplifier for your specific application. Several are shown below. See your dealer or visit

Installing a Wilson Outside Antenna
To receive the best cell signal, select a location in the center of the vehicle’s roof 12 inches
away from any other antennas and free of obstructions.
Follow the specific antenna installation instructions included with the outside antenna (sold
separately).
The outside antenna must be installed
vertically. Signal performance will be
degraded if the antenna is not vertical.
The antenna cable may be run through the
door to the amplifier.
The antenna cable is small enough to easily
tuck under the door seal or plastic molding.
For a more professional-looking installation,
the antenna cable may be run under the
door seal. Carefully pull down the door
seal. Run the cable through the seal
and push the seal back into place. This
prevents constant wear and tear on the
cable as the door opens and closes.
Warning: Do not use any type of glass-
mount antenna with this amplifier. The outside
and inside antennas must be shielded from
each other to prevent oscillation.

Installing a Wilson Amplifier
Warning: Do not plug in the DC power
supply until the outside and inside antenna
cables are attached to the amplifier.
!
Select a location to install the amplifier that
is away from excessive heat, direct sunlight
or moisture and that has proper ventilation.
Recommended installation locations are:
• Under the seat
• Under the dash
Run the cable from the outside antenna and
attach it to the FME-Male connector labeled
“outside antenna” on the amplifier.
Attach the inside antenna cable to the FME-
Male connector labeled “inside antenna” on
the amplifier.

Install the low-profile inside antenna 8-12
inches from where the cell phone or cellular
data card will be used.
Place the inside antenna on the side of the
driver’s seat for maximum performance.
Install the inside antenna at least eight
inches, but not more than 12 inches, from
where the cell phone or cellular data card
will be used.
Install the inside antenna at the same angle
as the cell phone when held in use, or place
next to the laptop’s cellular data card. This
will maximize the signal strength.
For a more professional-looking installation,
the low-profile antenna may be slid under
the seat cover or leather, high on the
driver’s seat.
Warning: Do not install the low-profile
antenna within four inches of metal. (Metal
found inside the vehicle’s seat will not affect
the antenna’s performance.)

Powering up a Wilson Amplifier
Make sure both the outside and inside
antenna cables are connected before
powering up the amplifier.
Connect the power cable from the DC
plug-in power supply to the amplifier
marked “Power” and insert the large end
into DC power socket (the cigarette lighter
outlet.)
The amplifier may remain on all the time.
However, leaving the amplifier on in a
vehicle when it is not running can discharge
the battery in a day or two.
A good option is to power the amplifier
through the ignition switch so the amplifier
is turned on and off with the vehicle.
NOTE: The aluminum casing of a Wilson amplifier will adjust very quickly to the ambient
temperature of its environment. For example, in the summer, when the inside of a car can
reach 140 degrees Fahrenheit, the amplifier temperature may be 150 degrees or higher.
The casing will be hot to the touch, similar to a metal door handle or a steering wheel. Such
high temperatures will not damage the amplifier, nor do they pose a fire risk to the vehicle.
As recommended in these instructions, install the amplifier in a location with adequate
ventilation, such as under the seat, in the trunk or under the dashboard. Keep the area free
of items that could block air flow to the amplifier.
Carefully insert the power cable.
IMPORTANT: Do not power up the ampli-
fier unless antenna cables are attached to
amplifier.
Warning: Use only the power
supply provided in this package. The
power supply must be 6 V DC.

Warnings and Recommendations
Warning: In a wireless installation, do not plug the amplifier directly into
the cell phone or cellular data card using an antenna adapter. It
will damage the cell phone or cellular data card.
Warning: Do not plug in the DC power supply until the outside and inside
antenna cables are attached to the amplifier.
Warning: RF Safety: The inside antenna must be installed with a
separation of at least eight inches from all persons and must not
be located in conjunction with any other antenna or amplifier.
Warning: RF Safety: The outside antenna must be installed with a
separation of at least 10 inches from any of the vehicle’s
occupants or nearby persons and must not be located or
operating in conjunction with any other antenna or amplifier. All
roof-mount antennas should be centrally located on the roof of
the vehicle. Mirror-mount antennas should be at least six inches
from the ground and leave at least 20 inches of separation from
any persons near or around the vehicle. Use of this cellular
amplifier with an antenna gain higher than 6.12 dBi is in violation
of FCC regulations for which the offender is fully liable. All
Wilson mobile antennas are 6.12 dBi or less.
Separation of inside and outside antennas is very important. The metal
roof of the vehicle acts as a barrier and helps shield the two antennas from
each other, preventing oscillation.
If the vehicle has a sunroof, it is important to separate the inside and outside antennas
by at least five feet. This prevents the amplifier from overloading or oscillating.
Distance between antennas
through a sunroof must be
5 feet or more.

Understanding the Amplifier Lights
The power light PWR will turn green
when the amplifier is successfully
powered up. When the 800 MHz or
1900 MHz lights are lit green, the
amplifier is amplifying the outside
signal.
If one or both frequency lights turn
red, oscillation is occurring and the
amplifier has powered down. The
outside antenna needs to be moved
farther from the inside antenna. Move
the outside antenna on the roof of
the car to the rear of the car, but at
least 8-12 inches from the rear or
side windows. Remove power from
the amplifier and reinstall power - this
resets the amplifier.
If the lights are now green, the
oscillation has stopped and the
amplifier is working. If the red light is
still on, move the antenna farther away
and repeat the process.
Always use a magnet-mount or roof-
mount antenna. Do not use a glass-
mount antenna, as oscillation may
cause continuous shut-down of the
amplifier.
An amber light in either the 800
MHz or 1900 MHz position indicates
overload from the cell site. The
amplifier has temporarily shut down
and will automatically reset.

Amplifier Usage 6 V, .5 A- 1.5 A (subject to uplink power)
Notes:
1. Nominal gain is the maximum gain at any frequency in the passband.
Average gains are: 37 dB (800 MHz uplink & downlink) 45 dB (1900 MHz uplink & downlink)
2. Nominal bandwidth is the difference between two frequencies that are adjacent to the passband where the amplification is 20 dB
lower than the passband amplification. One of the frequencies is lower than the passband and the other is higher.
3. 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.
4. The maximum power for 2 or more simultaneous signals will be reduced by 6 dB every time the number of signals is doubled.
