80dB/27dBm CDMA800MHz GSM850MHz AWS1700 Black and White Colors Mobile Signal Booster
Model:GW-27CA-NH
Signal Booster Description:
First off, we strictly tested all the boosters we sell in our lab to confirm their specs.
Specifically, we measured the following things for each booster:
Downlink Gain: Measures how much the signal coming from the cell tower is amplified
Uplink Gain: Measures how much the signal from your phone is amplified before being retransmitted to the tower
Max Downlink Output Power: Measures the maximum signal strength a booster can transmit indoors
Max Uplink Output Power: Measures the maximum signal strength a booster can transmit atback to the tower
Signal Booster Introduction:
Signal Booster GW-27CA-NH is designed to enhance and improve the quality of mobile 3G 4G LTE CDMA800MHz AWS1700 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.
