Installing a Wilson Amplifier
Select a location to install the amplifier that is away from excessive heat, direct
sunlight, moisture and that has proper ventilation. Do not place the amplifier in
an air-tight enclosure.
Recommended installation locations for in-building amplifiers are:
• On a wall
• On a desk
• Near a power outlet
Run the outside antenna cable to the amplifier and attach it to the connector
labeled “outside antenna” on the amplifier. Run the inside antenna cable to the
amplifier and attach it to the connector labeled “inside antenna” on the amplifier.
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 amplifier with low loss coax cable (available
from Wilson Electronics). Place the inside antenna in the center of the area
needing the amplified signal. It is important to have at least 70 feet of separation
between the antenna and amplifier.

Powering up a Wilson Amplifier
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 amplifier and antennas, make
sure that the distance between the inside and outside antennas is
a minimum of 68 feet of separation distance for the 60 dB PCS
amplifier, and 75 feet for the 60 dB cellular amplifier.
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 amplifier before powering up
the amplifier.
5. Plug the 6-volt power supply into the amplifier input marked “power”
(carefully, to avoid damaging the center pin) and then into a wall outlet.
NOTE: The aluminum casing of a Wilson amplifier 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 amplifier temperature may be 10 or more degrees higher. The casing will be
hot to the touch. Such high temperatures will not damage the amplifier, nor do they pose a fire risk.
As recommended in these instructions, install the amplifier in a location with adequate ventilation.
Keep the area free of items that could block air flow to the amplifier.
Warning: Verify that both the
outside antenna and the inside antenna
are connected to the amplifier before
powering up the amplifier.

Understanding the Indicator Light
The indicator light on the top of the amplifier will be GREEN when the unit
is powered up and working properly.
A solid ORANGE light indicates the amplifier has cut back it’s gain by
either 4 dB or 8 dB due to the amount of oscillation it is experiencing.
A blinking ORANGE light indicates the receiving or downlink signal on
either the 800 or 1900 band or both is overloaded and the amplifier has
shutdown either that particular downlink signal or both.
A RED light indicates amplifier shut-down as a result of oscillation
between the outside antenna and the inside antenna. When this occurs,
greater separation distance is required between the two antennas. If
you see the red light come on, followed by a green light and then back
to red, the amplifier is in the process of shutting down. It will attempt
to reset itself every five seconds; however, if proper separation is not
achieved between the antennas, the light will change to a constant red
after four tries. If that occurs, increase the separation distance between
the antennas, then unplug and re-plug the power supply cable to manually
reset the amplifier.
To reset the amplifier, unplug and re-plug the power supply.

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: The outside antenna must be installed on an outdoor permanent structure
with a separation of at least 20 feet from all persons during normal
operation.
Warning: Connecting the amplifier 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 amplifier
before powering up the amplifier.
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 amplifier 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 amplifier/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 amplifier 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 CoverageArea 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 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. The maximum power for 2 or more simultaneous signals will be reduced by 6 dB every time the number of signals is doubled.
