Installation steps

Step 1: Install the outdoor antenna on the roof or other positions where you can receive 4 bars of signal or more

Step 2: Connect the outdoor antenna to the BTS port via the cable and tighten the connectors at both ends, make the outdoor antenna point to the base station

Step 3: Connect the indoor antenna to the MS port, and place the indoor antenna at a higher position so as to increase signal coverage

Step 4: After connecting and tightening the two antennas, plug in the power supply and check the condition of the signal display light

Step 5: Check whether the phone signal has been improved or not. If it is not ideal, you can adjust the height or direction of the outdoor antenna. A good outdoor signal is half of the success.

Attention: There must be a solid wall between the indoor antenna and the outdoor antenna to prevent self-oscillation.

frequently asked question

After the installation, the signal improvement is not significant, and the indoor coverage area is small | 1. Adjust the position and direction of the outdoor antenna
2. Check if the cable is properly connected
3. Raise the outdoor antenna so that it can receive better signals
4. Replace high-power amplifier
5. Replace a high gain outdoor antenna
The phone signal is full, but the call quality is poor| The distance between outdoor and indoor antennas are too close, so it is necessary to increase the distance between them, or increase barrier isolation between them
After installation, the signal did not improve, but it was worse| The distance between outdoor and indoor antennas are too close, so it is necessary to increase the distance between them, or increase barrier isolation between them
I have been using it normally before, but suddenly the signal is not good after using it for a period of time| 1. Check if water ingress at outdoor cable joints
2. Check if the power indicator light is normal
3. If there is no water ingress into the cable and the power indicator light is normal, it is possible that the amplifier has malfunctioned and needs to be returned to the factory for repair

(3)the default antenna, cable, and/or coupling device that are shipped with the booster
Log-periodic Antenna, Panel Antenna and CoaxialCable.

(4) The antenna is equipped with a U-shaped mounting bracket. The log-periodic antenna should be installed in a place with good outdoor signal. The panel antenna should be installed indoors and near the main device. If the amplification effect is not good after the installation is completed, the direction of the log-periodic antenna can be gradually adjusted to achieve better effect.

(5) The device has automatic sleep function, strong anti-interference ability, over-power protection function, good heat dissipation design, and no radiation. The working noise is as low as 6DB.
