Reasons for Weak Cellular Signals
Anyone who uses a cell phone or cellular data card knows the frustration of not being
able to connect to or maintain a strong cellular signal. When this occurs, it’s generally
due to one of two reasons:
1. Location of the Nearest Cell Tower – Cell towers are situated to provide broad
coverage; however, there are many areas in which signal strength may be reduced by
local government restrictions on the height or placement of the towers themselves.
Rural areas generally have fewer cell towers than urban regions.
2. Natural and Man-Made Obstructions – Signal strength can also be negatively affected
by trees, hills, buildings and other obstructions. You may be relatively close to a cell
tower but still unable to make a call. This often occurs in homes, ofces and other
buildings in which stucco, concrete or metal walls block the signal.
The Adjustable Gain DB Pro works with two antennas. The inside antenna communicates
with your cell phone, and the outside antenna communicates with the cell tower.
The outside antenna receives the outside signal and sends it through the coax cable to
the Adjustable Gain DB Pro, where it is amplied and retransmitted through the inside
antenna into the room. When the inside antenna picks up a signal from your cell phone,
the Adjustable Gain DB Pro boosts that signal and transmits it through the cable to the
outside antenna and back to the cell site.
(Note: the Adjustable Gain DB Pro Signal Booster will only operate if there is adequate
signal to amplify.)

1 Select a location to install the signal booster that is away from excessive heat,
direct sunlight and moisture.
2Select a location on the roof of the building to install the outside antenna. Use a
cell phone in test mode to nd the strongest signal from the cell tower (see pg. 5).
Visit wilsonelectronics.com to nd the test mode function for your particular cell
phone.
3 Select a location for the inside antenna, preferably in the center of where the signal
needs to be amplied. Separation between the booster and the inside antenna
must be a minimum of 10 feet, to prevent oscillation.
4Verify that both the outside antenna and the inside antenna are connected before
powering up the signal booster.
Lightning protection is recommended for all in-building installations.
5Separation distance between the inside and outside antennas must be a minimum
of 50 feet, 75 feet is even better.
EASY TO INSTALL
The following steps provide a summary of the signal booster/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.

Installing a Wilson Signal Booster
Select a location to install the signal booster that is away from excessive heat,
direct sunlight, moisture and that has proper ventilation. Do not place the signal
booster in an air-tight enclosure.
Recommended installation locations for in-building ampliers are:
• On a wall
• In a closet
• Near a power outlet
Run the outside antenna cable to the signal booster and attach it to the connector
labeled “outside antenna” on the signal booster. Run the inside antenna cable to
the signal booster and attach it to the connector labeled “inside antenna” on the
signal booster.
Note: Be careful when plugging the connector in so as not to bend the center
pins on the connectors. Ensure cables have a tight connection.

Powering up a Wilson Signal Booster
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 signal booster and antennas, make sure that
the distance between the inside and outside antennas is a minimum of 50 feet,
75 feet is better.
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 signal booster before powering up the signal
booster.
5. Plug the 6-volt power supply into the signal booster input marked “power”
(carefully, to avoid damaging the center pin) and then into a wall outlet.
6. If using a panel inside antenna always point the panel antenna away from the
outside antenna. Signal Booster and inside antenna must have a minimum
separation of 10 feet, to prevent oscillation.
7. If you have a RED light on the front panel of your signal booster, adjust the gain
control corresponding to the frequency band for that particular light, slowly to
the left, until that light turns green. If the coverage area is insufcient after the
light turns green, try to re-orient the inside and outside antenna or both, until
the gain control can be increased without turning the light red.
8. If you know that only one frequency band (800 or 1900) is available in
your coverage area (or going to be used), reduce the gain control on that
frequency band that is NOT in use to the minimum. This will reduce the power
consumption of the signal booster.
The indicator lights on the signal booster will be GREEN when the unit is powered
up and working properly.
BLINKING RED LIGHT:
This signal booster has protection shut off circuits to prevent disrupting cell sites.
If your signal booster is in the process of shutting down (indicated by a blinking red
light on both, or either band) please refer to note 7 above. Then reset the signal
booster by removing power from the signal booster, make sure that no cell phones
are located within 50 feet of the inside antenna, then reconnect power to the signal
booster. If the red light is still blinking contact Wilson Tech Support for assistance
1-866-294-1660
A solid RED light indicates the signal booster has shut down to prevent oscillation.
Move antennas farther apart then reset the power. If red light is still on refer to note
7 above, in the Powering up a Wislon Signal Booster section.
To reset the signal booster, disconnect then reconnect the power supply.

Understanding the Signal Booster lights and troubleshooting
The Signal Booster is equipped with 2 indicator lights, to let you know if the
booster is working correctly. The indicator light on the left is for the 800 MHz
while the indicator light on the right is for the 1900 MHz band.

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 – this is to prevent oscillation.
Warning: Connecting the signal booster 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 signal
booster 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: RF Safety: FCC regulations require that any xed outside antenna used
with this signal booster may not have gain less cable loss that exceeds
15 dBi and must be located at least 30 inches from all people. Inside
antennas must not exceed 7 dBi gain less cable loss in the 800 MHz
band or 10 dBi gain less cable loss in the 1900 MHz band and must be
located at least 8 inches from all people.
Lightning protection is recommended for all in-building installations.
Finding Signal Strength and Calculating Coverage Distance
Signal strength and the corresponding coverage distance you can expect to achieve
with your signal booster/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 signal booster 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.
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.
Your inside and outside antennas will also add signal gain, again depending on the
antenna models you are using. You will also experience some signal loss from
cables, splitters and taps used to connect your system.
Warning: Verify that both the
outside antenna and the inside antenna are connected
to the signal booster 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.
