General
Your Wilson amplifier has been carefully engineered to significantly improve the performance of
your phone. Together with an outside antenna, the amplifier’s state-of-the-art circuitry is designed to
increase your phones signal to and from the cell site, up to 20 times greater than the phone alone. The
U-Booster™ reduces disconnects and dropouts and increases data communication rates on 2G and 3G
networks.
How it Works
With the phone in the cradle and while using a wireless Bluetooth headset (or wired hands free device)
the outside antenna collects the cell tower signal and sends it through its cable to the amplifier located
inside the cradle. The signal is then boosted by the amplifier and sent to the phone via the built-in
antenna inside the cradle. When the phone transmits, the signal is picked up by the antenna inside the
cradle, boosted by the amplifier and broadcast back to the cell tower via the outside antenna.
Before Getting Started
This guide will help you properly install the Wilson U-Booster™ Dual-Band Wireless Amplifier. It is important to read
through all of the installation steps prior to actual installation. If you do not understand the instructions contact
Wilson Technical Support at 866-294-1660.

Vehicle Installation
1. Place Magnetic Roof Top Antenna
To receive the best cell signal, select a location for the outside antenna that is preferably in the center of the vehicle’s
roof, 12 inches away from any other antennas and free of obstructions, at least 8-12 inches from the rear or side
windows or sunroof.
Carefully
Pull Down
Door Seal
Magnet-Mount
Antenna Shown
The outside antenna must be installed vertically. Signal
performance will be degraded if the antenna is not
vertical.
The antenna cable is small yet strong enough that it may
be shut in most vehicle doors without damaging the cable.
Run Cable
Under Seal
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 under the seal and push
the seal back into place. This prevents constant wear
and tear on the cable as the door opens and closes. The
antenna cable is small enough to easily tuck under the
door seal or plastic molding.
2. Attach the Mounting Bracket
Two mounting brackets are provided for attaching the U-Booster™ to your vehicle’s dash. Choose the appropriate
one for your application. See bracket specific mounting options below.
Option 1
Adhesive Bracket
1. Clean the area where the bracket is to be mounted with the
alcohol wipe provided. Allow to dry.
2. Peel the backing to expose the adhesive and press the bracket
onto the desired location in the vehicle. Note: be sure the tab is
positioned vertically, not horizontally.
3. Allow the adhesive to cure for 24 hours before you attach the
U-Booster™.
4. Once the cradle is attached, you can adjust the angle of the
adhesive bracket by applying gentle pressure to the top or bottom
of the U-Booster™. This option is designed to swivel when the
knurled nut is loosened, for greater adjustability of the U-Booster™
viewing angle. To lock bracket into position tighten large nut.
Option 2
Adhesive/Screw Swivel Bracket
This mount allows for adhesive mounting as well as more
permanent screw mounting. This option is designed to swivel
when the knurled nut is loosened, for greater adjustability of the
U-Booster™ viewing angle. For adhesive mounting, follow steps 1,
2 and 3 in option 1.
For screw mounting, use an ice pick or an awl to punch through
the adhesive and expose the four screw holes in the bracket. You
must provide the screws of an appropriate size for your particular
application. Using the bracket as a template, mark the locations
for the screws as shown, drill pilot holes, attach the bracket with
adhesive, and tighten all screws.
3. Attach the U-Booster™
Once you have installed your selected mount in the desired location, and waited 24 hours for adhesive to cure, attach
the cradle by aligning the rectangular hole on its back with the tab on the mount, grasping the sides of the cradle, slide
it downward approximately ¼ inch into place.

4. Powering up the Wilson U-Booster™ Amplifier
Make sure the outside antenna cable is connected before
powering up the amplifier.
Connect the mini-USB plug on the power cable to the U-Boosters
mini USB port located on the bottom of the U-Booster™ and insert the
adapter into the cigarette lighter outlet of your vehicle.
The U-Booster™ may remain on all the time. However, leaving the
U-Booster™ 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 U-Booster™ through the ignition switch
so that the amplifier is turned on and off with the vehicle. The 12 VDC
power source on many vehicles is shut off with the ignition key.
Note: With (optional) charging cables the U-Booster™ 5V power
supply provides charging current to the phone.
IMPORTANT: Do not power up the amplifier unless the outside
antenna cable is attached to amplifier.
WARNING: Use only the supplied Wilson power supply/connector to
power your U-Booster™.

Understanding the Amplifier Lights
Separation of U-Booster™ and the outside antenna is very important. In a vehicle, the metal roof acts as a
barrier and helps shield the two antennas from each other, preventing oscillation.
Oscillation can occur when the roof mounted antenna is too close to the U-Booster™ inside the vehicle. An
oscillation (or feedback) in an amplifier is similar to when a microphone is too close to a speaker in a sound
system, resulting in a loud whistle. An oscillation in a cellular amplifier, if allowed to occur, can affect nearby cell
sites’ ability to handle calls.
If the light turns red, an oscillation has occured and the amplifier has powered down to protect the cell tower.
The outside roof mounted antenna needs to be moved farther from the U-Booster™. In a vehicle installation,
move the outside antenna on the roof of the car farther to the rear of the car, but at least 8-12 inches from the
rear or side windows or sunroof. Remove power from the U-Booster™ and reconnect power - this resets the
U-Booster™.
If the light is now green, the oscillation has stopped and the U-Booster™ is working. If the red light is still on,
move the outside antenna farther away and repeat the process.
In a vehicle, 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 U-Booster™.

Building Installation
Installing a Wilson Outside Antenna in a Building
Follow the specific antenna instructions included with the outside antenna (sold separately except for certain kits). These
instructions assume that you are using a Wilson magnet-mount or mini magnet-mount antenna and the optional suctioncup window bracket.
To receive the best signal, select a window on the side of your building where your outside signal is the strongest.
Attach the suction-cup bracket to the inside of a window so that the cable
will reach the amplifier location. Place the bracket as high on the window as
possible for best performance.
Suction cup Antenna Window Mount -not includedAvailable from Wilson Electronics.
www.wilsonelectronics.com or call 800-204-4104
Once the bracket is in place, attach the magnet base of the antenna to the
flat surface of the bracket. Note: the antenna must be installed vertically.
Signal performance will be degraded if the antenna is not vertical.The
antenna cable is small enough to easily tuck under the door seal or plastic
molding.
Installing the Wilson U-Booster Amplifier in a Building
The Wilson U-Booster™ may be placed in any convenient indoor location, such as a desk or tabletop. The cell phone must be in the
cradle and a Bluetooth® headset used for voice communications.
Attaching the Antenna
Once you have selected the location for the U-Booster™, run the cable from the outside antenna and attach it to
the SMA connector on the bottom of the U-Booster™. Note: the U-Booster™ and the outside antenna must have a
minimum separation of 8 feet to prevent oscillation.

Troubleshooting
SYMPTOM: Green Light always OFF
1) Make sure that the power source is supplying power to
the U-Booster by checking that the light is on.
2) If the DC plug-in power supply is properly inserted,
but the plug’s light doesn’t come on, then check the
12 volts from the car socket, and check the fuse in
the DC plug-in power supply.
SYMPTOM: Red Light always ON
1) Make sure that the antenna connector is tight.
2) Place the outside antenna on its side (see picture).
Reset U-Booster™ power (off and back on) again.
The light should now be green (antenna was too
close). Turn U-Booster™ off and proceed to step 3.
3) Return the outside antenna to its upright position,
and move it further towards the rear of the vehicle,
(away from the U-Booster™) but no closer than 8
inches from a sunroof, rear or side windows. Power
U-Booster™ back on and recheck for a green light. If
light is still red, continue moving the antenna further
back and resetting the power until the light changes to
green and stays green. Remember to stay more than
8 inches away from a sunroof, rear or side windows.
4) If the light remains red, call Wilson Technical Support at 866-294-1660.
WARNINGS AND RECOMMENDATIONS
Warning:
Do not plug in the power supply until the outside antenna cable is attached to the
amplifier.
Warning:
RF Safety: The U-Booster™ cradle/amplifier must be installed with a separation of at
least 8 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 either a Wilson Magnetic-Mount or Mini
Magnetic-Mount antenna and requires at least an 8 inch seperation distance from all
persons. Other outside antennas may be used provided that (a) they are not within
a building, structure, or vehicle (b) they are located with at least a 30 inch seperation
distance from all persons, (c) their gain less cable loss does not exceed 15 dBi, and (d)
they are not operating in conjunction with any other antenna or amplifier.
Separation of U-Booster™ and outside antennas is very important. In a vehicle, the metal roof
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 keep the
outside antenna at least 8 inches from the edge of the
sunroof. This prevents the amplifier from oscillating.

NOTES
1. Nominal gain is the maximum gain at any frequency in the passband.
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. Data is in accordance with IC spec RSS-131. The maximum power for 2 or more simultaneous signals will be reduced by 6 dB
for each doubling of the number of signals.
