1 Select a location to install the amplifi er 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 fi nd the strongest signal from the cell tower. Visit
wilsonelectronics.com to fi nd test mode function for your particular cell phone.
3Select a location for the inside antenna, preferably in the center of where the
signal needs to be amplifi ed.
4 Verify that both the outside antenna and the inside antenna are connected
before powering up the amplifi er.
Lightning protection is recommended for all in-building installations.
5Separation distance between inside and outside antennas should be between
50 to 60 feet.

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
• In a closet
• Near a power outlet
Run the outside antenna cable to the amplifi er and attach it to the connector
labeled “outside antenna” on the amplifi er. Run the inside antenna cable to the
amplifi er and attach it to the connector labeled “inside antenna” on the amplifi er.
Note: Be careful when plugging the connector in so as not to bend the center
pins on the connectors.
Connect the outside antenna to the amplifi er with low loss coax cable (available
from Wilson Electronics). Place the inside antenna in the center of the area
needing the amplifi ed signal.

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 50 feet of
separation.
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.
6. If using a panel inside antenna always point the panel antenna away from the
outside antenna.
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.

Understanding the Indicator Lights
The indicator light on the top of the amplifi er will be GREEN when the unit is powered up
and working properly at maximum gain.
A solid ORANGE light indicates the amplifi er has cut back it’s gain by 8 dB due to the
amount of oscillation it is experiencing. If possible move antennas farther apart until you
get a green light.
A solid RED light indicates amplifi er is in shut down due to oscillation. Move antennas
farther apart then reset the power. If red light is still on move antennas farther apart,
continue this process until green light is on. If not enough distance is available you may
leave light orange at reduced gain but have less performance.
To reset the amplifi er, unplug and re-plug the power supply.

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
topographic features or 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, offi ces and other
buildings in which stucco, concrete or metal walls block the signal.
The Dual Band Wireless works with two antennas (included). The inside antenna
communicates with your cell phone, and the outside antenna communicates with the cell
tower. The outside antenna is designed for installation on a vent pipe or pole on the roof.
The outside antenna receives the outside signal and sends it through the coax cable to
the Dual Band Wireless, where it is amplifi ed and retransmitted much more strongly
through the inside antenna into the room. When the inside antenna picks up a signal
from your cell phone, the amplifi er boosts that signal and transmits it through the
cable to the outside antenna and back to the cell site. (Note: the Dual Band
Wireless Amplifi er will only operate if there is adequate signal to amplify.)

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 will result, causing amber light and gain
reduction.
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: FCC regulations require that any antenna (inside or outside)
used with this amplifi er may not have gain that exceeds 15 dBi. All
Wilson antennas meet this requirement. Inside antennas must have at
least 8 inches of separation from all persons. Outside antennas must be
farther than 39 inches from all persons.
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 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.
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.
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.

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.
