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 an optional directional donor antenna, 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. 4). Use of omni-directional antennas will require more
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 more separation distance compared to directional antennas
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.
Outside 800MHz RX
Indicator (Orange LED)
Outside 1900MHz RX
Indicator (Orange LED)
800MHz Gain Level
(Green LED)
1900MHz Gain Level
(Green LED)
Orange LED Lights (RX):
There two orange LED lights, one for the 800MHz cellular band and one for the 1900MHz
PCS band. LED ON state indicates that the RX (Receive Signal) function of the band is
functioning normally.
LED Off state indicates that the band is shut down.
Green LED Lights (TX):
There two Green LED lights, one for the 800MHz cellular band and one for the 1900MHz
PCS band.
Solid ON state indicates that the TX (Transmit Signal) function of the indicated band is on
and is at maximum gain.
Flashing Green LED in either 800MHz or 1900MHz indicates gain reduction in that band
Each flash equals 3db reduction in gain. One flash represents a 3dB reduction, two flashes
represents a 6dB reduction etc. until the total gain of the booster has been suppressed.
Causes of Flashing Green LED Lights:
1-If the outside antenna is located too close to the inside antenna or phone holder the
booster will reduce gain in order to suppress any oscillation (feedback loop) and the Green
LED will flash. To achieve higher gain or max gain further separation of the inside and
outside antennas is required.
2-If the booster is close to a cellular tower (Strong cell tower signal ) it will automatically reduce its gain to protect the network. This condition will change as the booster approaches
or leaves a cellular tower. This is normal and cannot be defeated or altered by the user.

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, you 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? Only 50 Ohm co-ax cable should be used. Please contact SmoothTalker for cables and connectors.

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.
