Antenna and Booster Installation
Donor Antenna: (outdoor signal antenna)
a) Location: There are three choices. fig. 2, 3, 4.
The choice of donor antenna location depends on the signal strength at the donor antenna
location. Use your phone to determine if signal at your chosen location is adequate. Better
signal level at the donor antenna location equals larger indoor coverage area.
b) Directional Donor Antenna: if using a directional donor antenna
supplied in the kit (Part# SEMD1), point the antenna toward the desired tower. If the location of the desired tower is not known, initiate a phone call and use the signal indicator on
your phone after the booster is operational, while turning the donor antenna, to determine
optimum donor antenna direction for maximum signal strength.
c) Omni-directional Donor Antenna: if using an omni-directional
donor antenna, it is recommended that it is placed as far as possible from the inside antenna, usually, ‘outside pole mount’ is recommended (Fig. 3). Use of omni-directional antennas
will require substantial separation distance compared to directional antennas. Fig. 1
Distribution Antenna: (indoor signal antenna)
a) Location: There are three choices. fig. 2, 3, 4.
The choice of donor antenna location depends on the area to be covered.
b) Directional Distribution Antenna: it is recommended that directional antennas
are oriented in a fashion that is back to back of each other Fig. 1
c) Omni-directional Distribution Antenna: it is important that omni-directional
antennas are separated as far apart as possible from each other. Use of omni-directional antennas will require substantial separation distance compared to directional antennas. Fig. 1
d) Splitting Indoor Signal: it is possible to use more than one indoor antenna to
cover areas that are separated by walls or floors by using antenna splitters or
power dividers, however splitters have a level of signal loss (3dB) and the added cable run
will also have signal loss, therefore the coverage area will be diminished. As a general rule, if
outside signal is good, splitting signal to more than one
distribution antenna results in reasonable coverage.
If outside signal is poor or marginal, splitting signal to more than one distribution antenna
results in decreased coverage for both distribution antennas.
Use only genuine SmoothTalker splitters. Contact your dealer or www.smoothtalker.com
Amplifier/Booster Location:
Install the repeater in a location that has proper ventilation, away from excessive heat and
moisture.
WARNING:
Make sure all cables have a good connection and are connected to the corresponding
antenna port on the Booster.
DO NOT APPLY POWER or turn on the power switch on the Amplifier/Booster
before all cables and antennas are connected.
Connection and Start Procedure:
Antenna connections must be snug and hand tight, ‘Do Not Use Pliers or Wrench’.
Connect the cable from outdoor antenna to RF port (antenna connector) labeled “Outdoor
Antenna”. Connect cable from indoor antenna to RF port labeled “Indoor Antenna”.
Connect supplied AC/DC power supply to the amplifier and plug it into power source.
Turn on the power switch on the Amplifier/Booster.

Control Panel: Understanding the Control Panel and LED lights
General: Mobile networks, phones and data devices operate in two frequency bands
(800Mhz & 1900Mhz). The Stealth Booster will amplify signals in both bands if they are
present. The band that the phone or cellular data device will transmit (TX) and receive (RX)
on is determined by the cellular provider and cannot be chosen by the user. The booster
LED lights will indicate outside signal level and booster gain. The ‘Master Control’ button
on the control panel will allow the user the option to increase gain, decrease gain or shut
off one or both of the frequency bands.

LED Light Brightness: the user can control the LED brightness of all LED lights by pushing
the up or down arrows on the control panel.
Outside Signal LED lights: three orange LED lights for each frequency band indicate outside RX signal strength (base station power) being amplified by the booster and transmitted into the building (Receive Power). This indicator is affected by two things : the outside
signal and attenuation that is applied by the user or the automatic controls of the booster.
The highest level signal being displayed by the booster lights can belong to any service
provider, not necessarily your service provider. To determine if your provider is the high
signal provider, start a call and place your phone at or close to the location of the donor
(outside) antenna and compare the phone signal bars to the LED indicator lights on the
booster. Note: if attenuation (gain reduction) has been applied by the automatic controls
of the booster or by the user, you may see low signal indication on the booster LED lights
even though the true outside signal is strong.

Gain Level: Understanding the Control Panel and LED lights
General: Four green LED lights for each frequency band will indicate the the level of amplifi-
cation that is being applied by the Booster to the receive (RX) signal and transmit (TX) signal.
Gain is applied to both RX and TX signals. Normally all four green LED will be solid on. If any
green LED lights are flashing or off, it is an indication that gain has been reduced. There are
four events that will cause the green LED lights to turn off or flash.
1) Shutdown:
a) Automatic shutdown will occur in one band or both bands if antennas are placed too close
to each other and the ‘Automatic Oscillation (feedback) Suppression’ function cannot eliminate
the oscillation. TX and RX gain will be turned off completely in the frequency band where oscillation cannot be suppressed.
b) Manual shutdown can also be achieved in one or both frequency bands by the user.
2) Oscillation (feedback) Suppression:
The booster will automatically apply attenuation (reduce gain) to suppress oscillation (feedback). This function is automatic and cannot be manually overridden.
3) High Power Control:
The booster will automatically apply attenuation (reduce gain) if RX or TX power is too high.
This function is automatic and cannot be manually overridden.
4) Manual Attenuation:
Gain can be increased or decreased manually by the user in 2dB steps over a range of 30 dB
for each frequency band, however, the user will not be able to reduce attenuation that has
been applied by the automatic oscillation suppression function or by the automatic high power
control function in order to protect both, the cellular tower and the booster.
Manual Gain Control
The master control button has 3 functions which cycle every 3 times pressed as follows:
1) 800mhz manual gain control Press once. The 3 orange LED lights for the 800 mhz band
will flash together. Use up or down arrows to adjust gain in this frequency band as desired.
Each push of the up or down button will adjust 2 dB of gain. Total manual adjustment range
is 30 dB. Adding more than 30 dB of attenuation will shut down the frequency band. Quick
shutdown of the frequency band can also be achieved by holding the down arrow. When the
frequency band shuts off all of the orange and green LED lights for that frequency band will
flash every 2 seconds.
2) 1900mhz manual gain control Press again. The 3 orange LED lights for the 1900 mhz band
will flash together. Use up or down arrows to adjust gain in this frequency band if desired.
Each push of the up pr down button will adjust 2 dB of gain. Total manual adjustment range
is 30 dB. Adding more than 30 dB of attenuation will shut down the frequency band. Quick
shutdown of the frequency band can also be achieved by holding the down arrow. When the
frequency band shuts off all of the orange and green LED lights for that frequency band will
flash every 2 seconds.
3) Manual gain LED display Press again to display the LED status of your inputed manual gain
settings then power the booster OFF/ON for manual settings to take effect. Each time you
cycle to this 3rd setting you will see your inputed manual gain settings displayed on the LEDs.
Note: the booster will remember manual settings through power on and off conditions. If you
want to return the booster to ‘Fully Automatic Mode’ you must go through step 1 and set the
800 MHz gain control to full gain (four green LED lights solid ON), then go through step 2 and
set the 1900 MHz gain control to full gain (four green LED lights solid ON). Power the booster
OFF and then ON for ‘fully automatic mode’ to take effect.
Important:
a) for manual settings to take effect, the booster must be powered OFF and then ON.
b) manual settings cannot override the automatic functions of oscillation and high power
controls. This means that if you are trying to set a gain level higher than the automatic control
functions allow, the manual gain settings will be limited by the automatic control functions.

Frequently Asked Questions
My booster is powered, running and the lights are on but my signal did not improve. Why?
Check your antenna connections and make sure they are snug. Also make sure that the external
and internal antennas are connected to corresponding antenna ports of the booster.
Should the booster get hot? Normal operation temperature for the booster is approximately 109°
F, or 43° C. This will feel warm to the touch.
Will the booster improve Voice and Data signals? Yes.
How large should my inside coverage area be? Coverage area is dependent on two factors; the
booster’s gain and the signal level at the outside antenna. It is possible to cover a large area with a
low gain booster if the outside signal is excellent, conversely, it is possible to have
relatively small coverage area with a high gain booster if the signal outside is really poor.
How do I increase my indoor coverage area? If your inside coverage area is inadequate, try to
move your external antenna to a location with better signal. If antenna location is optimized the
coverage area is still too small, use a higher gain booster. If outside signal is really poor and the
high gain booster does not increase the coverage area enough, use a line amplifier to increase
gain and TX power (pg 5).
Will the booster boost signals from service providers other than mine? Yes. Smoothtalker
Stealth series boosters are wideband RF amplifiers that will improve all Cellular and PCS signals
in your area.
Why does my friend’s phone show better signal than mine? Your friend’s phone is probably
using a different service provider that has a tower closer to your location than your service
provider. For best indoor coverage, make sure that your outside antenna is pointing at your
service provider’s tower.
Can I leave my booster on continuously? Yes.
Can I leave my booster on during a lightning storm? To be 100% sure that lighning will not
damage the booster, must unplug it from the wall and disconecct the external antenna from the
booster. If you must keep connected during lightning you can use a lightning arrestor on the
antenna and high quality surge protector on the power supply, however, Smoothtalker warranty
does not cover lightning damage.
I need more cable length. What do I use? For boosters with an N or X in the part number, only
50 Ohm co-ax cable should be used. For boosters with an F in the part number, only 75 Ohm coax cable should be used.

Troubleshooting Guide
LED indicators Action
Separate antennas and/or re-orient directional
antennas (back to back) and power OFF/ON the
booster.
Use control panel to increase gain to the desired level
in the chosen freq. band and power OFF/ON the
booster.
Gain has been reduced to suppress oscillation (feedback). Separate antennas and/or re-orient directional
antennas (back to back) and power OFF/ON the
booster.
Gain has been reduced to suppress high RX signal:
a) Directional donor (outside) antenna: turn to point
away from tower.
b) Omni antenna: change to a location with lower
signal.
Gain has been reduced to suppress high TX signal.
Normally temporary but if phone or cellular device is
constantly too close to inside antenna, move device
away from internal antenna.
Use control panel to increase or decrease gain to the
desired level in the chosen freq. band and power
ON/OFF the booster to set.

Glossary of Terms
Attenuation: the reduction of the RF signal usually measured in dB. Attenuation is the opposite
of Gain. Increasing attenuation has the same effect as turning down the volume control of a
radio or stereo speaker.
Booster: also known as: RF amplifier, repeater or signal enhancer.
dB: short form for decibel. Unit of measure for RF signal gain or attenuation.
Directional antenna: an antenna designed to focus its energy mostly in one direction.
Distribution antenna: internal antenna used to distribute signal to the interior of a
building or structure.
Donor Antenna: outside antenna used to provide signal from outside to inside.
Frequency band: the operational frequency range of the Smoothalker booster and the cellular
network frequencies that are amplified. These are commonly referred to as the ‘Cellular Band’
(824-894 Mhz) and the ‘PCS Band’ (1850-1990 Mhz).
Gain: the increase of the RF signal usually measured in dB. Gain is the opposite of
Attenuation. Increasing gain has the same effect as turning up the volume control of a radio or
stereo speaker.
LED: Light Emitting Diode.
Omni-directional antenna: an antenna designed to radiate its energy equally in all
directions.
Oscillation: term to describe a feedback loop. This occurs when the signal from one
antenna reaches the other antenna and the booster amplifies the signal creating a loop. This is
the same effect as the squeal one hears when a speaker is brought close to a microphone.
RF: Radio Frequency.
RX: ‘receive signal’ originating at a base station or tower.
Splitter/Power Divider: a component with input and output connectors that will allow one
originating signal to be split and distributed to two or more antennas.
TX: ‘transmit signal’ originating from a cellular phone or data device.
