              Q: Solution with no effect after installation?


              1. Firstly, it is determined that the signal strength of mobile phone signal at outdoor antenna end is more than 2 grids.


              2. Confirm that the amplifier, antenna and other accessories are selected correctly


              3. Confirm whether the indoor and outdoor interfaces, distributors and antennas of the mobile phone signal amplifier are connected correctly


              Q: After installation, the signal is improved, but no phone calls are made?


              1. Adjust the direction of outdoor antenna to receive stronger signal.


              2. See if the length of connecting wire can be shortened to reduce the loss of signal.


              3. Confirm whether the outdoor antenna is too close to the indoor antenna, and the received signal is from oneself, resulting in false signal.


              4. If it is not solved, replace the amplifier with higher power or ask professional personnel to check and deal with it.


              Q: Poor call quality?


              1. Adjust the direction of outdoor antenna.


              2. Change the direction of the signal transmission line from outdoor antenna to amplifier (take the nearest straight line, do not turn too much)


              3. Confirm whether 50 ohm coaxial cable is used for outdoor antenna to amplifier line.


              4. Confirm whether the distance between outdoor antenna and indoor antenna is too close (too close will form self excitation). It is required that the straight line should be more than 8-15m. The outdoor antenna should be more than 3m higher than the indoor antenna. It is better to isolate the wall, corridor and other objects to prevent the signal transmitted by the mobile phone signal amplifier from being received by the outdoor antenna to form cyclic amplification (self excitation).


              Q: After installation, the signal is improved, but the coverage is not large?


              1. Adjust the direction of outdoor antenna to receive stronger signal.


              2. See if the length of connecting wire can be shortened to reduce the loss of signal.


              3. Confirm whether the outdoor antenna is too close to the indoor antenna, and the received signal is from oneself, resulting in false signal.


              4. If it is not solved, replace the amplifier with higher power or ask professional personnel to check and deal with it.
