What ‘s In Box

​With the difference frequency of the booster, antenna need to be match so that it can work.

If you need 1800mhz/2100mhz, we will sent with the 9 Unit Yagi antenna.

If you need 850mhz/900mhz,we will sent with the5 Unit Yagi antenna.

The ceiling antenna is of 360° coverage, and the gain is higher than whip antenna which is directional coverage.You may installed the ceiling antenna in the place where you want to receive signal. Comparing with the whip antenna which only can install following to the booster, it’s better.

Easy To Install


Step1:Search a position where can receive good signal(stronger than -70dB)Parallelly installing the outdoor antenna on that location,towards to the base station or cell tower.

Step2: Use 10m cable to connect the outdoor antenna and singal booster.Please ensure they were tightenned joints,connected well. Step3:Connect the indoor antenna and the singal booster.

Step4:After finished all parts then check weather all connectors well,then can turn on the power.

Two antennas need to separate by brick wall. The distance between them at least 10 meters.

Working Principle


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


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


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

Band Story

Common Problems

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.

    The product corresponds to the declared characteristics of 3G, everything works without complaints (trial measurements). The apartment had indicators of 103 DBM, after the connection was 79 dBm. I was shocked, I called and no distortion, all the words are clearly heard. The seller is responsive, held a full consultation on the choice of the repeater. The repeater is small, the picture looks larger. The scoreboard is very small, not informative, it is not clear how it works (we will figure it out during the installation). Instruction in Russian language. Delivery mega fast, 9 days to Ukraine. Order, the seller is excellent).
