Before Getting Started
This guide will help you properly install Wilson’s In-Building Wireless Smart
Technology™ Amplifi 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, seek professional help, or contact Wilson Technical Support at
866-294-1660.
Inside this Package
• In-building wireless amplifi er
• AC/DC 110 volt power supply
Additional Required Equipment (sold separately)
• Outside Yagi antenna
• Inside dome, panel or low-profi le antenna
• Antenna coax cable
How it Works
Wilson amplifi ers are small, portable, bi-directional devices that deliver service levels
consistent with what would be expected in areas of high cell network coverage. They
amplify a weak or shadowed signal in mobile, marine and in-building applications.
When using a Wilson amplifi er in conjunction with Wilson antennas, the outside
antenna will collect the cell tower signal and send it through the cable to the
amplifi er. The signal is then amplifi ed and broadcast from the inside antenna
to the surrounding area. Cell phones and cellular data cards in that area then
communicate with the improved signal. When a cell phone or cellular device
transmits, the signal is received by the inside antenna, amplifi ed by the amplifi er
and broadcast back to the cell tower through the outside antenna.

Installation Overview
The following steps provide a summary of the amplifi er/antenna installation
process. However, they are not a substitute for the complete installation
instructions on the following pages, which you should read thoroughly. Contact
Wilson’s Technical Support Department with any questions at 866-294-1660.
STEP 1 Install the Outside Antenna
Mount the Yagi antenna so that it points toward the cell site and away from
where the inside antenna will be located. The two antennas will need 75 feet of
separation. (See illustrations on pages 5 and 7.)
STEP 2 Install the Inside Antenna
Select a location in the center of where the signal needs to be amplifi ed. Refer
to the instructions included with the inside antenna. (See illustration on page 6 to
determine the inside antenna model that best meets your specifi c needs.)
STEP 3 Install the Amplifi er
Position the amplifi er in a well-ventilated location near a power outlet. Attach the
outside and inside antennas to the amplifi er using 9913 or equivalent coax cable
(available from Wilson Electronics).
STEP 4 Power up the Amplifi er
IMPORTANT! Before connecting the power supply, ensure that both the inside
and outside antenna cables are connected. Also ensure that all cell phones and
cellular data cards within 50 feet of the inside antenna are turned off. Plug in the
supplied 6-volt power supply into the amplifi er and then into a wall outlet.
STEP 5 Check the Amplifi er Lights
The PWR light should be green, indicating that the amplifi er has power. If all
other lights are also green, the amplifi er is operating properly; however, if you do
not have the desired signal coverage area, refer to pages 5, 6, 9 and 10. (Note: if
you are using an outdoor Yagi antenna, it must be adjusted for maximum signal.)
STEP 6 If All Lights are Green Except Light D…
This indicates the combination of outside signals is too strong. Turn the outside
antenna slightly away from the cell site until all lights are green.
STEP 7 If Light A is Amber…
An amber light in the A position indicates the amplifi er is working but at reduced
gain due to oscillation. If you are satisfi ed with the signal coverage, no action
is necessary. If not, increase the separation between the inside and outside
antennas, then unplug the power supply and plug it back in to reset the amplifi er.
If you still have an amber light, repeat the procedure. (See “Troubleshooting” on
page 10.)
STEP 8 If Light A is Red…
A red light in the A position indicates the amplifi er has shut down, due either to
oscillation or to cell phone overload. (See “Troubleshooting” and “Cell Phone
Overload Protection” on pages 10 and 11.)
5
Select a location on the roof of the
building to install the outside antenna,
using a cell phone in test mode to fi nd
the strongest signal from the cell tower.
For test mode help, visit www.wilsonelectronics.com
or call Technical Support at 866-294-1660.
Installing a Wilson Outside Antenna
Follow the specifi c antenna
installation instructions included with
the outside antenna.
Lightning protection is recommended
for all in-building installations. Take
extreme care to ensure neither you
nor the antenna come in contact with
any electrical power lines.
A Yagi antenna must be installed
horizontally with the elements vertical
and the drip hole on the bottom.
Ensure there are three feet of
clearance in all directions surrounding
the antenna.

6
Installing a Wilson Inside Antenna
Select a suitable location for the inside antenna, preferably in the center of where
the signal needs to be amplifi ed. To determine signal strength and coverage
distance, refer to page 11 of this installation guide.
Follow the specifi c antenna installation instructions included with the inside antenna.
Wilson has several inside antenna options. The dome and panel antennas are
the most popular for in-building applications.
For a square room, a dome antenna will provide better coverage. (A)
For a rectangular room, a panel antenna will provide better coverage. (B)
In some cases, multiple inside antennas may be required (C & D). A signal may
be “split” by using a splitter. If using more than one inside antenna, a separation
of at least 20 feet is necessary between inside antennas.

Warning: An inside antenna must have
a separation distance from all persons that is at
least 8 inches from either the dome antenna,
panel antenna or other antenna with gain not
to exceed 7 dBi.

Installing a Wilson Amplifi er
Select a location to install the amplifi er that is away from excessive heat, direct
sunlight, moisture and that has proper ventilation. Do not place the amplifi er in
an air-tight enclosure.
Recommended installation locations for in-building amplifi ers are:
• On a wall
• On the ceiling
• Near a power outlet
Run the outside antenna cable to the amplifi er and attach it to the N-Female
connector labeled “outside antenna” on the amplifi er. Run the inside antenna
cable to the amplifi er and attach it to the N-Female connector labeled “inside
antenna” on the amplifi er.
Note: Be careful when plugging the connector in so as not to damage the center
pins on the connectors.
Connect the outside antenna to the amplifi er with 9913 or equivalent coax cable
(available from Wilson Electronics). Place the inside antenna in the center of
the area needing the amplifi ed signal. It is important to have at least 75 feet of
separation between the inside and outside antennas.

Powering up a Wilson Amplifi er
1. IMPORTANT! Ensure that all cell phones and cellular data cards within 50 feet
of the inside antenna are turned off.
2. To verify proper installation of the amplifi er and antennas, make sure that the
distance between the inside and outside antennas is a minimum of 75 feet.
3. If you are using an outside Yagi 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 amplifi er before powering up the amplifi er.
5. Plug the 6-volt power supply into the amplifi 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 amplifi er
before powering up the amplifi 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 amplifi 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 amplifi er
temperature may be 10 or more degrees higher. The casing will be hot to the
touch. Such high temperatures will not damage the amplifi er, nor do they pose
a fi re risk. As recommended in these instructions, install the amplifi er in a
location with adequate ventilation. Keep the area free of items that could block
air fl ow to the amplifi er.

Understanding the Amplifi er Lights
The amplifi er is equipped with sensitive electronics designed to detect amplifi er
oscillation or cell phone overload, both of which can hamper amplifi er performance.
The amplifi er is designed to automatically reduce gain or, if necessary, shut down
to prevent or compensate for these conditions. Oscillation or overload can be
caused by improper equipment installation -- understanding the amplifi er lights will
help you identify and solve potential problems.
The power light will turn green when the
amplifi er is initially powered on.
When all lights are green, the amplifi er
is working at proper gain level (peak
performance).
If lights A, B and C are green but D is out,
the combination of outside signals is too
strong and the amplifi er is powering down.
To remedy this, turn the outside antenna
slightly away from the cell site until all
lights are green.
If light A is amber, lights B and C are
green, and light D is off, the amplifi er
has reduced its gain by 10 dB due
to oscillation. Similar to placing a
microphone next to a speaker with an
audio amplifi er, placing the inside and
outside antennas too close to each other
will cause oscillation. In such a case,
although the amplifi er is still working
at reduced gain, the antennas need
more separation for optimal amplifi er
performance. See “Troubleshooting” on
page 10.
If light A is amber, light B is green, and
lights C and D are off, the amplifi er
has reduced its gain by 20 dB due to
oscillation. As above, the amplifi er is
still working at reduced gain, but the
inside and outside antennas need more
separation for optimal performance. See
“Troubleshooting” on page 10.
If light A is red, the amplifi er has shut
down, due either to oscillation or to cell
phone overload. See “Troubleshooting” on
page 10.

Troubleshooting
If light A is amber, this indicates the amplifi er
is working, but at reduced performance (gain
level). Increase the separation distance
between the inside and outside antennas,
reset the amplifi er by disconnecting and
reconnecting the power supply, then check to
ensure that light A is green. If it is not, repeat
this procedure. (Note: an amber light could also
be caused by a loose connector or bad cable.)
If light A is red, verify that the outside
Yagi antenna is pointed away from the
inside antenna and not across the roof of
the building. If need be, redirect the Yagi
antenna so that it is pointing away from the
inside antenna. Then, reset the amplifi er
by disconnecting and reconnecting the
power supply. See “Cell Phone Overload
Protection” on page 11.
If light A is still red, increase the separation
distance between the inside and outside
antennas. Then, reset the amplifi er by
disconnecting and reconnecting the power
supply. If light A is now green, there is
suffi cient antenna separation. If not, repeat
this procedure.
Note: in all cases in which greater antenna separation is needed, this separation increase can
be horizontal, vertical or both.
If all lights are green but you do not have the
desired signal coverage area:
• You may not be using the proper
antennas (see pages 5 and 6)
• The outside antenna may not be
pointed toward the strongest signal
• The inside antenna may not be
connected
• One or more coax cable connections
may be loose
• You may have a bad connector or cable
If you are unable to achieve the desired signal coverage with any of the above
troubleshooting steps, please contact Wilson Technical Support at 866-294-1660.

Cell Phone Overload Protection
If the cell phone is too close to the
inside antenna when making a call, it
can overload the amplifi er. To prevent
such overload, the amplifi er is equipped
with Automatic Gain Control, which
reduces gain. (Gain is indicated by
green lights in the B, C and D positions.)
One or more of these lights may go out,
indicating gain cutback. For example,
if light D is out but lights B and C are
green, this indicates minimum gain
reduction.
Maximum gain reduction is indicated if
lights B, C and D are all out.
If lights B, C and D go out and light
A shows red, the amplifi er has
automatically shut down due to
overload. Remove the power cable and
plug it back in to reset the amplifi er, then
move the cell phone farther from the
inside antenna while making a call.
If light A again shows red after moving
the cell phone farther from the inside
antenna and resetting the amplifi er
power, repeat the resetting procedure
and move the cell phone farther from
the inside antenna. If the red light once
again activates while making a call,
contact Wilson’s Technical Support
Department at 866-294-1660.
Warnings and Recommendations
Warning: The 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 protection will
result, causing red light and amplifi er shut-down.
Warning: RF Safety: The outside antenna must be installed on an outdoor
permanent structure with a separation of at least 14 inches from all
persons during normal operation.

Warning: Connecting the amplifi er directly to the cell phone with use of an
adapter will damage the cell phone.
Warning: Connect both the outside and inside antenna cables to the
amplifi er before powering up the amplifi er.
Warning: Use only the power supply provided in this package. Use of a
non-Wilson product may damage your equipment.
Warning: RF Safety: An inside antenna must have a separation distance
from all persons that is at least 8 inches from either the dome
antenna, panel antenna or other antenna with gain not to exceed
7 dBi.
Warning: NOTE: Use of this amplifi er with an inside antenna gain higher
than 7 dBi is in violation of FCC regulations. All Wilson mobile
and inside antennas have gains of 7 dBi or less for frequencies
applicable to this amplifi er. Use of this amplifi er with an outside
building antenna gain exceeding 13 dBi is in violation of FCC
regulations. All Wilson Yagi antennas have gains of 13 dBi or
less for frequencies applicable to this amplifi er. Use of antennas
with higher than the above maximum allowable gains is in
violation of FCC regulations for which the offender is fully liable.
Finding Signal Strength and Calculating Coverage Distance
Signal strength and the corresponding coverage distance you can expect to achieve
with your amplifi er/antenna system are based on a combination of several factors:
the received signal strength of your cell phone alone, the signal gain achieved by
your amplifi er and antennas, and the signal loss from cables, taps and splitters you
may be using.
To calculate your approximate signal coverage distance, you can enter this
information into our Coverage Area Calculator on the Technical Support page on our
website (www.wilsonelectronics.com). If you prefer, you can manually calculate your
approximate signal coverage distance using the instructions on this and the following
two pages.
First, measure the Outside Signal Level (OSL) at the intended outside antenna
location using a cell phone in test mode. (For assistance, visit the Phone Test Modes
section on the Technical Support page on our website or call 866-294-1660.) The
OSL will always be a negative number. (Even if the cell phone shows a positive
number, you will need to change it to a negative for this calculation.) Maximum signal
strength is usually about -50. When the signal weakens to about -100 or worse, the
call may be dropped.
Depending on the model, your amplifi er gain (AG) will be 50 or 60 dB (see the label
on your amplifi er). Your inside and outside antennas will also add signal gain, again
depending on the antenna models you are using (see the table on page 13).
You will also experience some signal loss from cables, splitters and taps used to
connect your system (see the table on page 13).

Splitter Factor (SF) -3 dB -3 dB -3 dB
Tap Factor (TF) (depends on model - refer to tap label) -6/-10 dB -6/-10 dB -6/-10 dB
Use the following formula to calculate your Signal Strength (S). Write in your numbers
as appropriate. Be sure to account for the length of all cable, inside and out. Add up the
numbers for all taps and/or splitters (if you are not using any, enter 0). Remember, AG and
AF will be positive numbers; OSL, CF, TF, SF and S will be negative.
OSL + AG + AF + CF + SF + TF = S
Once you have calculated your signal strength, use the graph on the following page to
determine approximate coverage distance. See below for a sample calculation.
Sample Signal Strength and Coverage Calculation
This example assumes an OSL of -90, use of a 60 dB cellular amplifi er, an 806-939 MHz
Yagi antenna and a low profi le inside antenna with 100 total feet of inside and outside 9913
cable with no splitters or taps.
OSL -90 (always a negative number) found on cell phone in test mode
AG +60 gain
AF +16 dB gain (+13 dB for the Yagi antenna and +3 dB for the low-profi le antenna)
CF -7 dB loss
SF 0 (none used)
TF 0 (none used)
Formula: -90 + 60 + 16 + -7 + 0 + 0 = -21
With a signal strength of -21, coverage distance would be approximately 120
feet from the inside 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 amplifi cation is 20 dB
lower than the passband amplifi 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.
