Package Contents
1. The outdoor antenna catches the signal from the tower.
2. Sends outside signal to the booster through a coax cable.
3. The booster amplifies the signal then rebroadcasts the signal indoors to all mobile
devices within range.
4. The system also works in reverse; amplifying outgoing signal back to the tower.
The kit includes the following items:
1. Outdoor Antenna, Indoor Antenna;
2. Booster;
3. Power supply;
4. Splitter;
5. 3*30 ft&1*15 ft of RG6 cable;
The size of the coverage area and the strength of the boosted signal are
directly related to two key factors:
1. The signal strength received by the outdoor antenna. Therefore, setting up
external antenna where the signal is strongest will provide the best results.
2. Distance of separation between the outdoor and the indoor antennas.

Note: FCC regulations limit the amplification of all cell phone boosters in order to
prevent damage to the telecommunications infrastructure. Therefore, the maximum
coverage area of a booster depends on the original power level of the signal captured by
the outdoor unit.
Notice: Not recommended when outdoor signal strength is less than -110dbm(3G/1x)
or -120dBm(4G/LTE). The resulting coverage area of the boosted signal will be
prohibitively small.

Find The dBm Reading On Your Phone
Having an accurate measurement of signal strength in decibels (dBm) is crucial when
installing your system. Decibels accurately measure the signal strength you are receiving.
Note: Turn off your cell phone’s WiFi to ensure you are checking the cellular connection.
The dBm reading will be refreshed every 30-60 seconds. Want faster results? Once you
have a reading, turn on airplane mode. Wait 15 seconds. Turn off airplane mode. The
signal strength reading is refreshed.

Step1: Select the Location for the Outside Unit
Note:This is the most critical step and will determine the overall performance of the
booster system.
1. Generally, the strongest signal will be located on the side of your home facing the
nearest cell tower. Keep in mind, the signal strength at ground level may be
different from the signal strength at or above the roofline due to obstructions
(trees, other buildings, etc.) that block the incoming signal. In most situations, the
strongest signal is found about 25 feet above the ground on the side of your home
facing the nearest cell tower.
2. The most ideal installation position is the corner of the building, choose the one
facing your cell tower.
8
Four corner of the building are the most ideal position
Choose the one facing your cell tower
Test Installation
We STRONGLY recommend doing a test installation before finalizing the installation.
Doing a test installation of your cell phone booster ensures that you will get the
optimal performance from your system.

Step 2: Temporarily Mount the Outside Antenna
In addition to the four corners of the building, the chimney and the pole above the roof
can also be selected. As long as the installation distance between indoor and outdoor
antennas is maintained enough, satisfactory results can also be achieved.
Use one of the three options to mount the outside antenna on your roof on the side of
the house with the strongest signal.
The height of the outside antenna should never exceed the highest point of your house.
This is a precaution against damage and safety concerns caused by lightning strikes to
the outside unit.
9
Caution
Trees will greatly attenuate wireless signals. If there are tall trees within 100 feet of the
house. At the same time you can't find a stable signal above 3 bars, the outdoor
antenna needs to be erected 60%(at least) to 80%(best) of the tree height. Never
exceed the trees!
But according to FCC
regulations, outdoor
antenna height cannot
exceed 30 feet.
At the same time, if the
antenna exceeds the roof,
please pay attention to
lightning protection
measures.

Step3: Select the Location for the Inside Antenna
Measure the Signal Strength Inside your Home
•Test your current signal strength in multiple locations throughout the home
•Record the current signal strength in the table provided for reference

In order to achieve the best signal coverage
effect, there is a certain distance requirement
between the indoor and outdoor units. Make
sure the inside and outside units are facing
away from each other.
Top view of antenna beam shape and energy distribution
•The radiation beam angle of indoor and outdoor antennas is about 90 degrees;
•In addition to signal radiation in front of the antenna, there is also energy radiation
behind the antenna;

The indoor antenna is a panel
directional antenna. Choosing a
location faceing all over your home
will help to maximize your coverage
area.
Step4: Connect the System
1. Connect the outside antenna to the 30
feet RG6 cable, fix the connector(In order to
avoid internal damage of the antenna
connector due to gravity or pulling the cable)
Secure the cable near the antenna
to prevent cable damage caused
by wind shaking

12
2.Connect the outside antenna to the
“OUTSIDE” port of booster.
3.Connect the 15 ft RG6 cable to the
booster at the “INSIDE” port.
6.Plug in the power adaptor and connect it
to the nearest power outlet (surge
protector recommended).
4.Connect the other end of the coax cable to splitter at the “INPUT” port, and two inside
antennas' cables connect to the other side port.
5.Connect the other end of the coax
cables to the panel antennas.

•Now that the booster is up-and-running, re-test the signal strength inside your home
at the same locations from Step 1. If the number is higher (dBm reading is closer to
zero) than the original reading, your booster is working.
•If your signal is not stronger, check the LED lights on the booster and refer to the
“Quick Troubleshooting” section at the end of the manual.

Step6: Finalizing Outdoor Antenna Installation
Outdoor Antenna Installation
Make sure that the outside unit is mounted at least 3 feet away from any windows.
Option A : Outside Roof Pole Mount
(Best Choice) Use an existing pole to
mount the outdoor unit in the optimal
signal location. Use the picture for
reference.
Once you have tested the performance of the signal booster and made all necessary
adjustments, it’s time to finalize the installation.
14
In particular, cables for outdoor antenna locations
must be fixed. Otherwise, the internal wires of the
cable will be pulled off after the wind has been
shaken for a long time. The amplifier will not receive
the signal and the system will fail completely.
As shown in the figure, it is best to have the cable
around a single turn shape and then fix it.
Long-term rain or moisture erosion
can damage the electrical
characteristics of outdoor antenna
connectors. Make sure connectors
are well screwed in and seal the
connectors with glued tape.
Secure the cable to
prevent cable
damage caused by
wind shaking
Seal and Fix the Connector
Option B : Mounting on the side of
the chimney(Second Choice).

Step8: Finalizing and Securing Cable Route
•Find the best route for the cable.
Follow the lines of your home to
hide the cable in eaves or
between the soffit and the
exterior wall.
•If needed, cable clips can be
purchased at most hardware
stores.
15
d. Mount the booster
•Choose a ventilated and dry place
•Keep away from heat
•Don't cover booster
Booster will about 30 degrees Fahrenheit
higher than the ambient temperature, which is a
normal phenomenon.
Step7: Finalizing Indoor Installation
a. Choose right position for the indoor antenna
•20 cm away from facing any other metallic objects
•50 cm away from any windows
•The inside antenna should be facing the location of the
signal dead zone/weak signal area inside the building
b. Mount the inside antenna
c. Connect the inside cable to the inside antenna
•Whether the cable is properly
secured is very important for the
entire system. In most cases, the
customer found that the booster
did not work after working for a
period of time because the cable
was not installed securely.
•Carefully arrange the cable along
the outside of the building and
ensure that there are no folds or
kinks. Fix the cable at each corner.

16
Make sure these excess coiled cables are more than 6 feet(2 meters) from the antenna
or booster can make your system work more stable.
If the coiled cable is too close to the antenna or booster, the system will be unstable.
Make sure these coiled cables are more than 6 feet(2 meters) from the antenna or
booster
Properly Handle Excess Cables
Caution
Secure the cable near
the antenna to prevent
cable damage caused by
wind shaking
Seal and Fix the Connector

Correct functioning:
•Power Light should be solid white( the logo on the panel)
•The indicator light on the front panel indicates the status of the booster. Every time
the booster is turned on, all the indicators will turn green for a period of time and
then go out. This means that the booster has passed the self-check and is in good
condition.

Trouble Shooting: No Signal Improvement
Step 1. Check power. Ensure the indoor unit is
plugged in and the LED Power Light is lighting.
The logo will be
illuminated
after the power
is turned on.
Step 2. Check cable connections. Ensure the indoor and outdoor units are securely
connected to the coax cable.
Step 3. Check incoming signal level at
outdoor unit position. Usage of a
booster is not recommend when the
outdoor signal is less than
-110dbm(3G/1x) or -120dBm(4G/LTE).
Step 4. Check your outdoor antenna
direction is faceing the tower which
coverage your house

18 18
Trouble Shooting: No Signal Improvement
Step 6. If any of the lights on the front panel are flashing in green then off/continue
flashing/solid green, it means that self oscillation is occurring. You must switch off the
booster and check the outside and inside antennas' seperation immediately. Make
sure that the Minimum Separation Requirements have been met. Make sure that the
outside antenna is not pointed towards the inside antenna.
Minimum Required Separation Distance Between Indoor and Outdoor Antenna：
Straight line distance over 30 feet(10 meters)
or
20 ft (6 meters) horizontal distance
13 ft (4 meters) vertical distance(As far as possible)
Step 5. Trees will greatly attenuate wireless signals. If there are tall trees within 100 feet
of the house. At the same time you can't find a stable signal above 3 bars, the outdoor
antenna needs to be erected 60%(at least) to 80%(best) of the tree height. Never
exceed the trees!
