Do you choose a correct cell phone booster for your house?
A cell phone could use different frequency band at different locations, it is very
important to confirm if your cell phone works on same frequency band as the cell
phone booster.
If it confirms that you purchase a wrong booster for your house by doing the test below,
please feel free to contact us at [e-mail], we will assist you to swap for a
correct booster.
Please be patient to do several tests around your house and check if all test results are
same. If there are more cell phones in the house, please do the test on all cell phones.

Test Installation
Where to install the outside antenna? The position,
where the outside antenna is installed, it can bring a
significant impact on the booster performance.
To point directly the cell tower, it aims to receive the best
signal and prevent the signal interference.
The higher position, it might avoid the impact caused by
the big obstruction between the house and the cell
tower.
ATTENTION: If the house is metal siding, do NOT install
the outside antenna or the outside unit directly on it.
Keep away from metal surface as much as you can.
When installing the booster and the antennas, we do
require Minimum Separation Distance between the
outside antenna and the inside antenna.
Minimum Required Separation Distance：
6 meters (20 ft ) distance and 4 meters ( 13 ft ) vertical
height distance. (see Self Oscillation section) For some
critical location, it might requires further separation.

Test Installation:
Doing a test installation of a cell phone booster, it allows you to experiment different scenarios to
determine your optimal system setup. SolidRF STRONGLY recommends doing a test installation
before the permanent installation.
Why?
1. To decide where to place the outside antenna, the booster and the inside antenna.
2. To determine Route the cable inside
the house.
3. Doing a test installation will simplify
the process if the system you
purchased was not ideal for your
situation. In this event, please contact
us by email, [e-mail]

Quick Installation
Find the Strongest Signal
1
Use your cell phone to find where the strongest signal is around your house. Check the signal bar on
your cell phone, or try to download. Please be patient and repeat the signal check multiple times. We
STRONGLY recommend a test installation first before anything is permanently secured.
Exterior Antenna Installation
2
Mount the exterior antenna on the roof (recommended) of an outside wall where is without
obstruction. Connecting the coax cable to the antenna, then secured by waterproof tape.

Connect to Inside Unit
3
Connect the coax cable from the exterior antenna to the inside unit; Connect the interior antenna onto
the inside unit.
Setup Inside unit
4
It aims to create sufficient isolation between two antennas, you should maintain at least 13 feet(4
meters) vertical distance and 20 feet(6 meters) horizontal distance between two antennas.

Antennas Installation Recommended
Antennas Installation Prohibited
It MUST satisfy the separation distance
requirement.
Do NOT point the outside antenna to inside.
If the vertical separation distance could be over 6 meters (20 ft.), the horizontal separation
distance can be less.

Plug the Power Adapter
5
Plug the AC power adapter to the inside unit. It recommends to use a surge protected power strip for
the device. If the booster is installed correctly and working properly, the power light would be solid
green. NOTE: If there is any question or concern, please refer to the troubleshooting or contact us at
[e-mail]
Antennas Installation Prohibited
Do NOT point the outside antenna to any big
obstructive, like building, hill, tree or wall.

ATTENTION: Self Oscillation
We strongly recommend it must achieve the Minimum Required Separation Distance for the
installation. The improper installation could result in possible Self Oscillation.
Minimum Required Separation Distance (MRSD)：6 meters (20 ft ) distance and 4 meters ( 13 ft )
vertical height distance.
When the antennas are too close, they could pick
up each others signals, creating a feedback loop
condition, which is called Self Oscillation.
By FCC regulations, the cell phone booster would
automatically detect this condition and
immediately shut down to prevent Self Oscillation
from damaging the cellular network.
(see TroubleShooting)
What is Self Oscillation:
If the booster detects Self Oscillation, it
will not operate until the condition is
corrected. One way to correct Self
Oscillation is to increase separation
distance between the antennas until the
sufficient separation distance is
achieved. Also the antennas can NOT
directly face each other.
How to correct Self Oscillation:
The Self Oscillation could cause interference to the cellular network, The FCC regulations
extremely prohibit cell phone booster users from causing interference to the cellular networks. If
you were contacted by the FCC or any wireless provider –yours or any other –and told your cell
phone booster is causing interference, you must shut it down until you can fix the interference
problem. Under most situation, it is Self Oscillation problem.
Please refer to:
https://www.fcc.gov/wireless-telecommunications/signal-boosters/faq/signal-boosters-faq.
Why is it so important to prevent Self Oscillation:

STEP BY STEP INSTALLATION
Step 1: Mount the booster outside unit
a. Choose right position
•Find the strongest signal position in the
possible install locations by reading your cell
phone signal bar (see Find Strongest Signal)
•Stay away from any big metallic objects
•100 cm away from any windows
b. Connect the cables as required (see the
picture below)
•The booster outside unit is integrated with
the exterior antenna and the signal amplifier,
ideal to improve system performance.
•Make sure connectors are well screwed in
c.Mount the booster outside unit on the mount
pole (not included) with U bolt. The outside unit
is recommend to install on the mount pole over
the roof, it would help to provide sufficient
isolation between two antennas.
Installation - Step By Step
How does it works
Step 1: The powerful outside antenna captures
a voice and data signal and transfers it to the
booster.
Step 2: The booster receives the signal,
amplifies it and then rebroadcasts the signal by
the inside antenna.
Step 3: Your mobile devices will get a better
signal, never experiencing dropped calls or slow
data speed.
