If you find that you must be near a window or outside to get adequate cell phone reception, then this cell phone booster is the solution. There are a number of reasons why you may be experiencing poor reception. The most common reasons are: [ 1 ] Distance from the cell phone tower [ 2 ] Obstructions caused by terrain, trees, buildings [ 3 ] Energy efficient windows and other construction materials.
[ 1 ] Step-by-step instructions [ 2 ] External Antenna [ 3 ] 10 meters of coax cable [ 4 ] Base Unit: Amplifies the signal and provides oscillation protection for the carrier network [ 5 ] Indoor Antenna: connects to the Base Unit and repeats the signal to create an indoor cell zone.

[ 1 ] Mount the External Antenna where you have the strongest cell phone signal, typically on a roof or in an attic.
[ 2 ] Connect the internal antenna to the Amplifier Base Unit and place where you need improved signal. Indoor antenna should connect “MS” end of Amplifier. There should be a minimum of 2 vertical meters of separation between the Base Unit and External Antenna.
[ 3 ] Run the coax cable (10 meters) between the Base Unit and External Antenna. External antenna should connect with “BTS” end of repeater.
[ 4 ] Connect the power supply to the Amplifier Base Unit and plug into a power outlet and you are done!
