How it Works
Your new Wilson SOHO Wireless Dual-Band Amplier has been carefully engineered to
enhance the performance of your inside or cellular data card in small ofce/home ofce
applications. Its advanced technology is designed to signicantly improve voice and
data signal quality and reduce disconnects and drop-outs. The amplier works with two
antennas (sold separately): one communicates with the outside (the outside antenna) and
the other communicates with your inside or laptop data card (the inside antenna).
The outside antenna will collect the outside signal and send it through a cable to the
amplier. The signal is then boosted and sent through a cable to the inside antenna, which
communicates with your inside or data card. When the inside or data card transmits, the
inside antenna picks up the signal and sends it to the amplier where it is boosted and
sent through the outside antenna to the outside.
Wilson Electronics manufactures a wide variety of antennas and accessories to help you
customize your SOHO Wireless Dual-Band Amplier for your specic application (see
page 2). Contact your dealer or visit www.wilsonelectronics.com.
Before Getting Started
This guide will help you properly install Wilson’s SOHO Wireless Dual-Band Amplier. It is
important to read through all of the installation steps for your particular application
prior to installing any equipment. Read through the instructions, visualize where all
the equipment will need to be installed and do a soft installation before mounting any
equipment. If you do not understand the instructions in full, please contact Wilson technical
Support at 866-294-1660.
Installation Overview
The following steps provide a summary of the amplier/installation process using a Yagi
antenna as the outside antenna and a panel antenna as the inside antenna. However,
they are not a substitute for the complete installation instructions on the following pages,
which you should read thoroughly. Be sure to read and follow the instructions that come
with your specic antennas.
STEP 1 Install the Outside Antenna
Mount the Yagi antenna to a xed location (such as a pole) on the roof of your building. Be
sure it is pointing toward the nearest cell tower and away from where you plan to install the
inside antenna. IMPORTANT: The outside antenna must have a separation of at least
24 inches from all persons during normal operation.
STEP 2 Install the Inside Antenna
Attach the panel antenna as close as possible to the center of the area where the signal
needs to be amplied. Ensure there is a minimum separation of 20 feet between the
outside and inside antennas. IMPORTANT: The inside antenna must have a separation
of at least 8 inches from all persons during normal operation.
STEP 3 Install the Amplier
Position the amplier in a well-ventilated location near a power outlet. Attach the antennas
to the amplier using 50-ohm or equivalent coax cable (available in different lengths from
Wilson Electronics).
STEP 4 Power up the Amplier
IMPORTANT! Before connecting the power supply, ensure that both the inside and outside
antenna cables are connected. Also ensure that all insides and cellular data cards within
20 feet of the inside antenna are turned off. Plug the supplied 6-volt power supply into
the amplier and then into a wall outlet.

4
Installing the Outside Antenna
The antenna that communicates with the outside should be mounted on the outside of the
building—this is the preferred location and will give the best performance. Alternatively,
locating this antenna inside the building near a window will also work under certain
conditions. IMPORTANT: The outside antenna must have a separation of at least 24
inches from all persons during normal operation.
Outdoor Installation
For best results, use a Wilson Yagi antenna that is compatible with the frequency of your
cellular service provider. A dual-band trucker antenna will also work. Mount the antenna as
high as possible on your building for optimum signal reception and transmission.
Follow the specic installation instructions included with the outside antenna. Lightning
protection is recommended for all outdoor antenna installations. Take extreme care to
ensure neither you nor the antenna come in contact with any electrical power lines. Ensure
there are three feet of clearance in all directions surrounding the antenna.
Alternate Installation
If you choose to install the outside antenna
indoors, select a location near a window or
glass door where you have the strongest
existing cell signal. (See the illustration on
page 5.) Follow the specic installation
instructions included with the antenna.

Installing the Inside Antenna
The antenna that communicates with your inside or cellular data card should
be installed in the center of where the signal needs to be amplied. Wilson’s
magnet-mount, mini magnet-mount, dome and panel antennas will work well with
the SOHO Wireless Amplier.
Warning: The inside antenna
must have a separation distance from all
persons that is at least 8 inches.

desk). Follow the specic instructions included with the antennas for your specic
application.
Warning: Connecting the amplier
directly to the inside with use of an adapter
will damage the inside.
!

6
Installing the Amplier
Select a location to install the amplier that is away from excessive heat, direct
sunlight, moisture and that has proper ventilation. Do not place the amplier in
an air-tight enclosure.
Recommended installation locations are:
• On a desk or table top
• In a bookshelf
• On the oor
In the illustration below, a Wilson Yagi antenna is being used as the outside
antenna, and a Wilson dome antenna is being used as the inside antenna.
Run the outside antenna cable to the amplier and attach it to the FME-male
connector labeled “outside antenna” on the amplier. Run the inside antenna
cable to the amplier and attach it to the FME-male connector labeled “inside
antenna” on the amplier.
Note: Be careful when plugging the connectors in so as not to damage the
center pin.
Connect the outside antenna to the amplier with 50-ohm or equivalent coax
cable (available in different lengths from Wilson Electronics). Place the inside
antenna in the center of the area needing the amplied signal. It is important
to have at least 20 feet of separation between the inside and outside antennas.
Closer spacing may result in oscillation, which will cause the amplier to
automatically reduce its gain.

Powering up a Wilson Amplier
1. IMPORTANT! Ensure that all insides and cellular data cards within 20 feet of
the inside antenna are turned off.
2. To verify proper installation of the amplier and antennas, make sure that the
distance between the inside and outside antennas is a minimum of 20 feet.
3. If you are using an Yagi antenna as a outside antenna, never point the front of
the Yagi toward the inside antenna.
4. Ensure that both the outside antenna coax cable and the inside antenna coax
cable are connected to the amplier before powering up the amplier.
5. Plug the 6-volt power supply into the amplier input marked “power” (carefully,
to avoid damaging the center pin) and then into a wall outlet.
Warning: Verify that both the
outside antenna and the inside
antenna are connected to the amplier
before powering up the amplier.
!
Warning: Use only the power
supply provided in this package.
Use of a non-Wilson product may
damage your equipment.
!
NOTE: The aluminum casing of a Wilson amplier will adjust very quickly to the
ambient temperature of its environment. For example, in the summer, when
the attic of a house can easily exceed 100 degrees Fahrenheit, the amplier
temperature may be 10 or more degrees higher. The casing will be hot to the
touch. Such high temperatures will not damage the amplier, nor do they pose
a re risk. As recommended in these instructions, install the amplier in a
location with adequate ventilation. Keep the area free of items that could block
air ow to the amplier.

8
Understanding the Amplier Lights
The power light PWR will turn green
when the amplier is successfully
powered up.
When the 800 MHz or 1900 MHz lights
are lit green, the amplier is amplifying
the outside signal.
If one or both frequency lights turn red,
the amplier is oscillating. To correct
this, you must increase the separation
between the inside and outside antennas
until all lights are green. After increasing
the separation, it is necessary to turn the
amplier power off and back on to reset
the red lights. If one or both frequency
lights remain red, repeat this procedure
until both are green.

9
Warnings and Recommendations
Warning: A Yagi antenna must always be located so the back or side points
to the inside antenna. Never point the front of the Yagi antenna
toward the inside antenna – oscillation will result, causing amber
light and gain reduction.
Warning: Connecting the amplier directly to the inside with use of an
adapter will damage the inside.
Warning: Connect both the outside and inside antenna cables to the
amplier before powering up the amplier.
Warning: Use only the power supply provided in this package. Use of a
non-Wilson product may damage your equipment.
Warning: The outside antenna must have a separation distance from all
persons that is at least 24 inches. The inside antenna must have
a separation distance from all persons that is at least 8 inches.
Lightning protection is recommended for all in-building installations using an
outside antenna.

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 amplication is 20 dB
lower than the passband amplication. 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.
