80dB 27dBm GSM 900MHz Cell Phone Signal Boosters with LCD Display
Model. GW-27G-NH
Why do you need a signal booster ?
Cell Phones have become an indispensable part of modern day lives. From our first breath to our last in the day, we ensure we keep our cell phone close. The cell phone alone is not what fancies us. There’s constant need to stay connected, the fear of “losing out” in life or being “left behind”, better known as nomophobia. Although technology has progressed immensely in helping the signal reception reach our doorstep, that is not always the case - Voices are not always quite clear to be comprehensible, mobile internet becomes sluggish and seems to take forever to load Internet pages or Youtube videos due to weak signal, and the worst is the problem of dropped calls altogether.
Signal Booster Introduction:
Signal Booster GW-27G-NH is designed to enhance and improve the quality of mobile 2G GSM900 connection.There’re black and white colors for options.
The gain of the model is 80dB, the power is 27dBm, which is compatible with all domestic operators of mobile communication. It is ideal for using in houses, offices, shops and restaurants.
The model is equipped with an LCD screen, which indicates the level of input signal before and after boosting. The information on the LCD screen, greatly simplifies the process of adjusting the gain of the system.

FAQ:
1. After installing booster signal not be very good, indoor signal coverage very small ?
> Adjust outdoor antenna's location and direction
> Change another high gain outdoor antenna
> Check whether cables are connected well
> Change more powerful repeater
2. Cell phone signal full bar, but communication quality bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.
3. After installing booster not only signal be good, but also more bad ?
> Much closer distance between indoor and outdoor antenna, separate them with a longer distance.
4. Working good for long time, suddenly signal bad ?
> Check whether outdoor cable connectors are flooded
> Check whether power light is working normally
> If cables are not flooded and power light is working normally, the booster should has problems and need to be sent back to factory for repair.
