Working Diagram (How It Works)

1. The outside antenna catches the signal from the tower, transmit it through a coax cable into the booster.
2. Booster amplifies the signal and then transmit it through a coax cable to the inside antenna.
3. The inside antenna rebroadcasts the signal inside to all mobile devices within range.
4. The system also works in reverse; amplifying outgoing signal back to the tower.

The size and the coverage area and the strength of the boosted signal are directly related to two key factors:

1. Signal strength received by the outside antenna.
2. Distance of separation between the outside antenna and the inside antenna.

Package Contents

Signal transmission loss and power level

Coverage area ability

Note: FCC regulations limit the amplification of all cell phone boosters in order to prevent damage to the telecommunications infrastructure. Therefore, the maximum coverage area of a booster depends on the original power level of the signal captured by the outside antenna.

Notice: Not recommended when outside signal strength is less than -110dbm(3G/1x) or -120dBm(4G/LTE). The resulting coverage area of the boosted signal will be prohibitively small.

Find The dBm Reading And Band Number On Your Phone
Having an accurate measurement of signal strength in decibels (dBm) is crucial when installing your system. Decibels accurately measure the signal strength you are receiving.

Note: Turn off your cell phone’s WiFi to ensure you are checking the cellular connection. The dBm reading will be refreshed every 30-60 seconds. Want faster results? Once you have a reading, turn on airplane mode. Wait 15 seconds. Turn off airplane mode. The signal strength reading is refreshed.

Step1: Study your vehicle and make a installation planning

In order to achieve the best signal coverage effect, there is a certain distance requirement between the inside antenna and outside antenna. Make sure that the outside antenna is horizontally attached to the roof and the inside antenna is parallel to the horizontal plane.

First determine the location of the inside antenna. It should be the place you use your cell phone signal most of the time.

NOTE: It is suggested that the inside antenna should be placed at the lower side of the driver’s seat, so as to maximize the distance from the outside antenna. Be sure it’s in a location that the cable can reach.

Step 2: Find position for outside antenna

Then choose the location of the outside antenna. It should be rear on the roof, has the most distance from the inside antenna location. Also need consider how the route the cable inside. We suggest the installation location with green identification, please refer to ….

Step3: Outside Antenna Installation

Determine where you want the cable to enter the vehicle.

NOTE: With two options

Option A: Enter the car through the back door

Option B: Enter the car through the trunk and pass through the rear seats

Determine where you want to have the outside antenna on your vehicle.

There is a powerful magnet at the bottom of the outside antenna, which can attract the device to the surface of ferrous materials

Make sure that the outside antenna is horizontally attached to the roof.

Step4: Inside Antenna Installation

There are 2 powerful celcro at the bottom of the inside antenna, which can attract the antenna to the side of seat.

Note: Make sure that the inside antenna is parallel to the horizontal plane

Step5: Connect the System

Step6: Evaluate the Effects

• Now that all of the components of the booster are in place, and the booster is powered on, it’s time to check the performance. If everything checks out, return to steps 2 and 3 to finalize installation. Here’s what you should look for:
  1.) Run a signal strength/speed check. Test the signal strength with the booster off, then re-test the signal in the same location after you plug-in the power supply. You should have a stronger signal. You can access the signal strength through the settings menu of your phone (a negative number in dBm) or download a speed test App. Remember that a stronger signal means the dBm is closer to zero.
  2.) When you plug-in the power adaptor, the booster runs a self-diagnostic as it powers on. Use the LED light on the panel to interpret the results. If everything is connected properly, and there is an adequate power supply, the LED light should flash 1 second and then go off.

• If something is wrong, refer to the “Quick Troubleshooting” section at the end of the manual. Otherwise, finalize the installation. Happy boosting, happy trails!

How to visually confirm that your installation is effective and correct?

At a distance of 1 feet from the indoor antenna, test the signal strength without obstruction. If this test result is 15~20db higher than your test result at the outdoor antenna position, then your system has reached the best effect.

For example, you test a signal of -90dbm at 1 feet away from the indoor antenna. Your outside antenna position record is -105dbm. So the improvement is:
-90dbm – (-105dbm) = 15db

If your results do not reach this range, please check your installation or contact us.

Note1: In daily life, the signal dbm readings of our mobile phones range from -70dbm to -120dbm. Because it is a negative number, the smaller the number, the greater the signal strength.

Note2: In the case of no problems with the installation, the strength of the indoor signal depends entirely on the strength of the outdoor signal.

Trouble Shooting: No Signal Improvement
