Introduction
With the popularity of mobile communications, people want to make a call anytime, anywhere,
so the coverage requirement of communication network is higher and higher, but the reality is
not so, sometimes mobile phone signal is not very good, you want to make a smooth call, even in
some places cell phone cannot dial out. in this cases, cell phone signal booster can solve this
problem in a certain extent.
Features
■ AGC(Automatic Gain Control): When the downlink output signal is too strong or self- oscillated,
the uplink and downlink can automatically reduce the gain and reduce the interference signal
■ Self- Oscillation elimination: The system detects self- Oscillation, first reduces the link
gain, then detects the loop, and finds that the self- oscillation is eliminated, the system returns
to normal working state, otherwise, the power is turned off to prevent interference signal.
■ Inactivity Mode: When no user calls, the device is in standby mode, the uplink power amplifier
is switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy
saving.

INSTALLATION INSTRUCTIONS
（1）Installation of Outdoor Antenna
The booster’s main function is to improve weak RF signals of an area. A simple formula:
Input power+ Gain= Output power. The signal strength from the outdoor antenna directly
affects the efficiency of the indoor coverage. It is very important to choose the outdoor
antenna location in order to get the best signals.
5/10
Testing the signal strength received from outdoor antenna mounted in site by
mobile phone:
Please select the top of building to install the outdoor antenna if total floors are less
than 7 floors, and shall try your best to select places like balcony or platform lower
than 7th floor for outdoor antenna if the buildings are over 7 floors, because the
mobile signals are clean at less than 7th floor.
The mobile phone shall display full bar signals in location where the outdoor
antenna is installed
The phone calls or data transmission shall be smooth and stable by 3 times testing
in location where the outdoor antenna is to be installed
As shown from the above illustration, testing the signals from A to E, and select a
best place that displays full bar signals to install the outdoor antenna.
Selecting the installation direction of outdoor antenna.
The outdoor antenna shall point to the direction of the tower, and it would be much
better to keep line of sight.
Please select the opposite directions for outdoor antenna and indoor antenna. If
outdoor and indoor antennas have to be installed in the same direction, please
install them only after the signal quality is tested and the self-oscillation is avoided.
If the directional antenna is selected, the main directional angle should point to the
tower antenna.
If the performance is poor due to weak signals or poor phone call quality, please
adjust the direction of outdoor antenna or change its position in order to obtain the
best calling effect.
The wide band booster supports all mobile operators or different mobile systems,
so please adjust the outdoor antenna direction to have balance between signals of
different mobile operators or various mobile systems.
Connect the outdoor antenna to the booster connector marked OUTDOOR with 10
meters 3D-FB Coaxial cable with N male connector.
Important: Outdoor antenna installation ---Notes:
In order to avoid interference, please note that the outdoor antenna should be far
away from the following objects of metal, high-voltage line, RF antenna and
high-voltage transformer.
Booster is a two-way signal Booster. So proper isolation between outdoor antenna
and indoor antenna is necessary in order to avoid self-oscillation.
The minimum distance between outdoor antenna and indoor antenna shall be more
than 10 meters; again the direction of outdoor and indoor antennas shall be opposite.
As shown in the below illustration, the booster the downlink signal r from the tower
6/10
and send to the indoor antenna hereafter. If the distance between outdoor antenna
and indoor antenna is less than the required distance, the amplified signal R will go
back from indoor antenna to outdoor antenna. So it will lead to self-oscillation and
reduce the coverage area, also the bad calling quality could happen at the same time,
and the worse is that the mobile network could be influenced badly and the operators
will finally come to shut off the booster system.
If isolation can’t be achieved by the limited distance, the roof of the building or any
other barriers can be used in between to increase isolation.
Fix the donor antenna after selecting the best position, and adjust slightly its height
or angles in order to get the signals with suitable input power level and calling
quality.
WARNING:
The Outdoor Antennas for fixed installations must be installed no higher than 10 meters above
ground.
（2）Installation of Indoor Antenna
Proper antennas shall be selected according to the site conditions and the
requirement.
Omni antenna (Indoor ceiling omni antenna or whip antenna), is suitable to be
installed in the center and radiate all directions.
Indoor antenna must be operated at a fixed location inside a building, it is better to
use a directional panel antenna when the coverage building is long and narrow.
Connect the indoor antenna to the booster connector marked INDOOR with 5 meters
7/10
3D-FB Coaxial cable with N male connector.
Notes：Indoor antenna must be operated at a fixed location inside a building.
（3）Booster Installation
Do not place the equipment in direct sunlight or in an area that has abrupt
temperature and humidity changes.
it is suggested that the booster is installed in a cool，dry and ventilated room without
erosive gas and smoke.
Connect power adaptor to the booster，connect The other end of power adaptor to the
power outlet.
WARNING:
The input voltage for the booster is +5V DC. DO NOT use this Booster with a regular
power supply that NOT +5V . otherwise, it will be damaged and the user may also be
injured.

frequency band is correct.
3. Check whether the indoor and outdoor antenna is installed correctly
4. At the location where the outdoor is installed, if your mobile phone is
able to receive a stable 3 bars cell phone signal, If not, find a location
where the mobile phone can receive a better signal to install the outdoor
antenna.
5. Whether or not your house is a metal roof. If so, you will need to set
up your outdoor antenna at least 3 meters above the roof.
Booster has
effect ,but the
effect is not ideal
Check if your outdoor signal is very weak. If you can only receive one or
two bars cell phone signal in the outdoor.
If so, contact our customer service and ask to replace the booster or
antenna with a higher gain alternative.

Mobile phone
can receive full
signal, but can
not normally
make a call
It Usually means that the booster is self-oscillated, please make the
distance between the indoor and outdoor antenna as far as possible, it is
better to use a wall or metal to Separate the indoor antenna and the out
door antenna.
During using your Booster, if the Booster interferes with your radio or other electronic
device, move the Booster further away from those devices, you might be able to solve it
yourself.
