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:

  • In-Building Signal Boosters - They are designed for homes, office buildings, commercial buildings, and any building that needs signal.
  • Vehicle Signal Boosters - They are designed for cars, trucks, RVs, SUVs, boats, and fleet vehicles.

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:

  1. An External Antenna – Used to capture the weak cell phone signal.
  2. An Amplifier – Used to boost the weak signal.
  3. An Indoor Antenna – Used to rebroadcast the enhances signal inside your home, office, or car.

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.

User's Manual

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.

Select the different systems when you need,

(only for Dual band, Tri band, Quad-band or Five band repeater.)

 

Features:

1. Cost effective solution for weak signal zones, reduce drop/off calls.

2. Compact size, low power consumption, easy installation, great cover.

Expansion and extending of the signal of base station.

Optimization of the quality of the signal and source

3. Cover about 3000~6000m² without block or obstruct.

4. High linear design, ALC function design, low interference to BTS.

5. Support any cellular devices (voice & data & video)

6. Wide band signal booster, or customize selective band booster.

 

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.

FAQ

9,FAQ.jpg

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
