Dear All,

Please pay attention before you place the order:

If you need, Please choose the signal (2G/3G/4G) you want first and check it as below ,

Or you can download "LTE Discovery " app to check .

Put your phone there to check its signal strengthness outside:

1. Please check frequency range first when you plan to buy signal booster . Frequency doesnrsquot match, the signal booster canrsquot works.

2. Please make sure outdoor or roof the signal of the corresponding frequency is good, otherwise this product canrsquot help you. It needs outdoor good signal to improve your indoor signal.

3. The last but not the least, please install follow our installation steps. If really canrsquot works, please contact us attached pictures or video, so that we can help you check. Donrsquot just open disputes without any communication.

Our signal booster/Amplifier can help you solve the problem.

1.Sarch a position where can receive good signal(stronger than -70dB.)

2.Parallelly installing the outdoor antenna on that location,towards to the base station or cell tower.

3.Use 13m cable to connect the outdoor antenna and signal booster.

Please ensure they were tightenned joints,connected well.

4.Connect the indoor antenna and the signal booster.

5.After finished all parts then check weather all connectors well, then can turn on the power.

Working Priciple

1. RECEIVES SIGNAL

The powerful antenna reaches out to access a good signal, and delivers it to the booster.

2. BOOSTS SIGNAL

The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

3. BROADCASTS SIGNAL

Your devices get increased cell reception, and calls and data are fed through the booster back to the network.

Question: no signal on the display and phone

Solution: adjust outdoor antenna, put it at a higher postion and make sure it could receive good signal from base station.Or please check the freqeuncy of your antenna, if you buy only booster from us. If the frequency doesn't match to the booster's, it could not work either.

Question: the display is blinking and signal light isn't on.

Solution: Also adjust outdoor antennna as above, because blinking means receiving signal is not stable. Adjust the position and direction of outdoor antenna until it stop working.

Queation: the signal is at maximum on booster but the signal on the phone does not improve at all

Solution: It is what we called "self-oscillation phenomenon". You need to increase the distance of indoor antenna and outdoor antenna and separae them with a brick wall. Make sure there is no opening area between them.

Question: The booster works properly but the signal light is not on

Solution: Maybe the cable is too long for the booster or the connection is not well. Please make sure all the antenna are connected well and tightly. It actually does n't matter too much as long as the device works well.
