With the development of the times, mobile cell phone signal booster are also commonly found in households. Guangdong Amplitec Tech Development Co.,Ltd has collected some problems encountered in the installation of mobile phone signal amplifiers, and sorted out four common problems and solutions. If the problem still cannot be solved, please contact us.

First, the treatment method that has no effect after installation

        1. Make sure that there is a mobile phone signal at the outdoor antenna end with a signal strength of more than 3 bars.

        2. Make sure 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.

Secondly, after installation, the signal is improved, but no phone calls can be made

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

        2. See if you can shorten the length of the cable to reduce the loss of the signal.

        3. Confirm whether the outdoor antenna is too close to the indoor antenna, and the signal received is the signal sent by itself, resulting in false signals.

        4. If it has not been resolved, replace the amplifier with a higher power or ask a professional to check and deal with it.

Third, the call quality is not good

        1. Adjust the direction of the outdoor antenna.

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

        3. Make sure that the line from the outdoor antenna to the amplifier is a 50-ohm coaxial cable.

        4. Confirm whether the distance between the outdoor antenna and the indoor antenna is too close (too close will cause self-excitation), the straight line is required to be more than 8-15 meters, the outdoor antenna is preferably more than 3 meters higher than the indoor antenna, and it is best to be separated by walls, corridors and other objects Open to prevent the signal emitted by the mobile phone signal amplifier from being received by the outdoor antnna to form cyclic amplification (self-excitation).

Fourth, the signal is improved after installation, but the coverage area is not large

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

        2. See if you can shorten the length of the cable to reduce the loss of the signal.

        3. Confirm whether the outdoor antenna is too close to the indoor antenna, and the signal received is the signal sent by itself, resulting in false signals.

        4. If it has not been resolved, replace the amplifier with a higher power or ask a professional to check and deal with it.

        In addition, the quality problem of the mobile phone signal repeater itself is the fundamental reason that affects the use effect, so we must choose a good mobile phone signal amplifier. As the largest mobile phone signal booster manufacturer in the world, Guangdong Amplitec Tech Development Co., Ltd not only has good product quality, but also Has the best after-sales service and is the designated partner of multiple operators around the world.
