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.

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.
