65dB 17dBm 2G GSM 900MHz Cell Phone Signal Boosters for Reduce Dropped Calls
Model. GW-17G-V
Signal Booster Description:
Provide every mobile carrier's cell phone, tablet, hotspot, or other mobile device with extra signal. It dramatically reduces the chances of missed and dropped calls, improves data speed, and allows you to enjoy lighting fast internet and text message speeds.
It works just the same for all cellular models like Apples iPhones, Samsungs, LGs, HTCs, OnePluses, ZTEs, Motorolas (Motos), Googles Pixels XL/ Nexuses models, Kyoceras, Blackberrys, Microsofts Lumias, and Nokias. The kit is also built for maximum convenience, and you do not need to attach your device to a docking station. When not in use, the GreetWin kit's signal becomes dormant, so no power is wasted.
How does a signal booster work ?
A cell phone reception booster is generally a repeater system that involves the amplifier adding gain or power to the reception in various directions. Even for a cheap cell phone signal booster, maximum gain differs by application. The work of an outside antenna is to both receive and transmit signal to a cellular tower with enhanced power and sensitivity. Usually the dB gain is never below 7 dB and can be over 10 dB gain. The system's elements conduit is the coaxial cable. It is also a factor in transmission loss.
Signal Booster Introduction:
Signal Booster GW-17G-V is designed to enhance and improve the quality of mobile 2G GSM900 connection. There’re black and white colors for options. The Led Indicator will show the current level of the input signal, which simplifies the installation of the external antenna. High quality aluminum shell provides an optimal cooling. This model, as simple in connection, installation and configuration, does not require special skills.

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.
