A cell phone signal booster (also known as a signal extender, signal amplifier, or cell phone repeater) works by pulling in weak outside signal, boosting it, and rebroadcasting the boosted signal into the desired areas. They also work in reverse: the signal booster will receive the signal from your phone and send it back to the tower.
There are different boosters available that target different needs:
Keep in mind that for a cell phone signal booster to work, there must be an existing signal outside your home, office, or vehicle. A cell phone signal booster enhances existing signal, it does not create it.
Most signal booster kits are composed of three main elements:
Coax cables are used to connect the top three elements; they are designed to deliver high-frequency electrical signals over distances with low signal loss.
For more information on coax cables, see our guide on Understanding Coaxial Cables.
| POWER LED | Green | Normal |
| Off | DC power problem | |
| ALARM LED | Green | Sys-1,Sys-2 or Sys-3, working in linearity |
| Red | There are strong input signal or severe self oscillation. Attention: input signal level is too high or the space of donor antenna and service antenna is not enough. please adjust the gain, If the red light still turning on that means over accepting of donor antenna or strong interference, then please adjust the place of donor antenna. | |
| Off | Repeater breaks down, Please re-plug in and check if Alarm LED turns red, if it is, please take measures to keep Alarm LED green; if it maintains off, it means the power break down. | |

Advantages:
Digital Display Panel, Intelligent mode setting
Smart function called which can be activated via the digital display panel.
Users can choose gain and working system by LED Digital Panel.
Set the technical parameters simple and efficient, this is easier than DIP Switch.
Standard Package:
1) AC90-264V, DC 9V/5A power supply adapter 1PCS
2) AC power cord (EU/US/UK/SA/China standard, etc) 1PCS
3) Installation kit 1PCS
4) User manual 1PCS
Application Diagram:
Q1. Why is there still no signal after installing the equipment?
1. Check the power on booster and power supply.
2. Check the connector of outdoor antenna is tight or not.
3. Check the connectors of RF cable are tight or not.
4. Check the outdoor signal is strong enough or not.
5. Check to make sure the antenna is installed correctly.
6. Check the connector of indoor antenna is tight or not.
7. Check the cable type is suitable or not.
Q2. Why the signal strength is too weak on the edge of area?
1. Check the outdoor signal and antenna direction.
2. Check booster is full gain or not.
3. Check all of the connectors are tight.
4. Change the location of outdoor/indoor antenna.
5. Check the cable type is suitable or not.
6. Deploy more indoor antennas.
Q3. After running booster, why the signals are not stable?
1. Checking the distance between donor antenna and server antenna are too close to each other? Check LED
of booster to make sure alarms are green.
2. Checking the signals from donor antenna whether to be stable or not?
3. Connect the system again if it is incorrect connection.
Q4. Why the booster power LED is not bright?
1. Checking the input AC power range indicated on power adapter whether is corresponding to the local
power system.
2. Checking the power adapter whether connect the equipment correctly and stably or not.
3. Checking the power adapter whether damage or not. To test output voltage whether be corresponding to
that indicated on power adapter or not by multimeter
