Feature:
1. Wide Coverage: The signal amplifier adopts the indoor antenna transmission, strong penetration, wide coverage, signal no dead angle. Covering an area of 100‑800 square meters,
2. Intelligent Chip: The intelligent chip greatly increases the signal, covers a wider range, and has strong multi directional penetration.
3. Block Radiation: The cell phone signal amplifier is made of high quality aluminum material, effectively block radiation, let the radiation close to 0, environmental protection and energy saving, low loss. Simple installation.
4. Automatic Control: Various frequencies are suitable for different countries and regions, all machines adopt automatic gain control, stable performance.
5. Wide Application: Wide scopes of application, suitable for hotels, shopping malls, villas, duplex buildings, large family houses, etc.

The Mobile Phone Shows Full Signal, Can Not Call the Solution:
A. This situation is caused by the insufficient uplink power of the amplifier or the weak signal of the outdoor antenna
B. Confirm that the distance between indoor antenna and outdoor antenna is more than 12 meters39.4ft, and it is best to separate indoor and outdoor antenna with a wall
C. Confirm that there is mobile phone signal at the outdoor antenna end, and if the well reaches above (-50bm), whether the signal indicator scale is full..

FAQ:
1. No effect after installation
A. first confirm that there is A mobile phone signal at the outdoor antenna end, and reach (above ‑50DM, whether the signal indicator scale is fully displayed.
C. Confirm that all lines and connections of distributor, antenna and amplifier are correct.
2. After installation, the signal is improved, but you can"t make a phone call
A. Confirm that the outdoor antenna is aligned with the base station.
B. Confirm that the communication distance between the outdoor antenna and the base station is within 5 kilometers.
C. Confirm that the line between outdoor antenna and amplifier is not more than 40 meters131.2ft, not more than 20 meters65.6ft is more appropriate, and not less than 10.
3. The call quality is poor.
A. Change the installation position and indicating direction of the outdoor antenna.
B. Change the direction of the signal transmission line from the outdoor antenna to the amplifier (take the most direct and nearest line, and don"t turn too much, don"t turn 90 degrees right Angle).
C. Confirm whether the outdoor antenna to amplifier line adopts 5070 ohm 50 or more coaxial electricity.
D, confirm whether the distance between outdoor antenna and indoor antenna is too close (too close will form self excitation), try to distance more than 20 meters65.6ft, it is best to have walls, floor and other objects apart, to prevent the signal emitted by indoor amplifier is received by indoor antenna to form circular amplification (self‑excitation).
4. Signals are intermittent
A. this situation is caused by the amplifier self‑excitation.
B. The processing method is to confirm that the input and output connectors are correct and the shielding is good.
C. Confirm that the distance between indoor antenna and outdoor antenna is more than 12 meters39.4ft, and it is best to separate indoor and outdoor antenna with a wall.
