How it works
B-25K
The signal booster’s outside
antenna receives voice and
data signals from a nearby
cell tower.
Receives Signal
The inside antenna
distributes the boosted
signals inside your building.
Improves Signal
The signal booster receives
the signal from the outside
antenna and amplies the voice
and data signals.
Boosts Signal
YagiAntenna
American Booster B-25K has been designed to improve and extend cellular coverage inside
the buildings. B-25K amplies signals from the nearest base station and re-transmits them at higher
power level. B-25K provides service at 700MHz LTE, 850MHz Cellular, 1900MHz PCS and 2100MHz AWS
frequencies without any additional setup or conguration.

STEP 1. Find the Strongest Signal
Installation Guide
1-1. Using an iPhone
Dial *3001#12345#*, then press Call.
1-2. Using an Android
Download the ‘Network Signal info’ from the Google Play store.
After installing, you will be able to view your dB strength.
1-3. Using a Meter
If you have a meter that detects and displays the current signal levels, you can use it.

Note The stronger signal you receive from the base station, the better coverage you will have
inside your building.

STEP 2. Install the Outside Antenna
The outside antenna must be mounted outside the building with the strongest cell signals.
Mount the outside antenna as high as possible facing towards the desired location of the
cell tower and facing the opposite direction of the expected location of the inside antenna.
For the best performance, a minimum of 50 ft. distance between outside antenna and inside
antenna is recommended. The bigger the separation distance from the antenna, the higher
the coverage provided by the booster. However the smaller the separation distance, the lower
the coverage provided by the booster.

STEP 3. Run the Outside Antenna Cable
Note TV cables already being used for other purposes can not be shared with the cell
booster during installation.

To Lightning Protector
Outside Antenna
to 2 ft. cable
When mounting the outside antenna to the outside wall of your building, the easiest way is
to run the cable on the outside of the wall and attach it to the exterior of your oce & building.
Then drill a hole through the wall which will allow the cable to appear on the inside of the
building. To avoid any potential harm or damage, make sure that there are no electrical outlets,
sewer water pipes, or electrical wiring in the wall before drilling.
After drilling the required hole, run the cable through and seal it.
In some instances, it may be possible to run the cable up into the fascia of the attic overhang.
In this circumstance, the cable will be accessible in the attic further routing.

Choose a location for the signal booster, preferably away from excessive heat, direct sunlight,
moisture and is free from high temperatures. Do not place the signal booster in an air-tight
enclosure. Attic installations may expose the booster to high heat.

DescriptionLED Status Troubleshooting
Green indicates the Signal Booster
is powered, and working properly. No troubleshooting is required.
AC/DC adapter is damaged.
Or
AC outlet does not provide power.
Verify that AC/DC adapter’s cable is
not damaged.
Or
Check if the AC outlet is working
and not controlled by a wall switch
that can cut power to the outlet.
Isolation between the outside and
inside antennas is being
checked now.
It will take up to 25 seconds.
No troubleshooting is required.
Isolation between the outside and
inside antennas is good and the
Signal Booster is working properly.
No troubleshooting is required.

DescriptionLED Status Troubleshooting
Outside antenna and Inside
antenna are not isolated enough
from each other.
So the Signal Booster is shutdown
at this frequency.
Change the position of Outside
and Inside antennas. Make sure the
Outside antenna is not facing towards
your own roof or at the inside antenna
as this will cause isolation issue and
the signal booster will stop amplifying
signals at this frequency.
Uplink Signal coming from the outside
antenna to Base Station is too strong
and may cause troubles to carriers
network, so the Signal Booster stops
service at this frequency.
Change the position of Outside
and Inside antennas. Make sure the
Outside antenna is not facing towards
your own roof or at the inside antenna
as this will cause isolation issue and
the signal booster will stop amplifying
signals at this frequency.
Signal from BTS station is too weak.
Change the position of Outside
antenna to receive stronger signal
from Base Station.
Outside antenna and Inside antenna
is not isolated enough from
each other.
Change the position of Outside and
Inside antennas. Make sure the
Outside antenna is not facing towards
your own roof or at the inside
antenna as this will cause isolation
issue and the signal booster will not
be able to amplify signals at
maximum power.
Status LED is red.
Output bars are ashing green.
The Signal Booster works properly.
Flashing Red during 30 mins,
then Solid Red.
