How does a cellular amplifier work?

Cell phone amplifiers improve cell phone reception by filtering cellular signals and amplifying them. Typically an external antenna is placed outside the building, car, RV, or truck. This antenna is used to send and receive signals from the nearest cell phone tower. The received signal is transferred through a cable to an amplifier unit, which filters the signals, amplifies them, and then transmits them via cable to an internal antenna that rebroadcasts the signal. By using a cell phone amplifier, you can achieve full bars on your phone in an area where you previously had no reception.

 

The introduction of the ST-3G&2w specification:

Use ALC circuit;There is Standing wave alarm dir cuits in;When the outdoor antenna and indoor antenna at a same level or at a very short distance, SWR red LED will also keep lighting and it shows that the amplifier is self-ex-citied, so we need to adjust the direction and high of the outdoor antenna. If it is impossible to adjust the outdoor antenna, then you can adjust the ATT tumbler switch.

3 Connect the outdoor antenna to ''outdoor'' port in repeater machine through cable

4 Connect the indoor antenna to ''indoor'' port in repeater machine through cable

5 Plug the power adaptor into AC power socket and finish installation

 

Please be noted while installing:

The distance between the outdoor antenna and the amplifier is not more than 30 metersThe outdoor Antenna not close to a large antenna, high-voltage lines, transformers, or metal mesh, etc.The distance between the indoor antenna and the amplifier is not more than 40 metersThe indoor antennas do not close to the wall as far as possible in order to increase the coverage areaThe indoor antenna and the outdoor antenna are advised to stay away from each other for more than one floor distance to prevent cyclic signal amplificationIf lack of communication quality, please change the installation position of the outdoor antenna and adjustment the indicate direction of antennaIt is best to enclose waterproof tape at the junction, and prevent moisture narrow the indoor signal coverage areaTry to straight the cable, do not bend more than 90 degree
