Product Description

Tri Band 1800MHz / 2100MHz / 2600MHz Cell Phone Signal Boosters Increase Signal Strength

Model. GW-20DWL-NH
 

Reasons Why Your Signal Is Weak

One of the reasons why your cell phone reception is weak could be due to the distance from the cellular tower closest to you. The closer you're to the cell tower, the stronger the cell phone signal received. On other hand, the farther you're from the cellular tower of your carrier, the worse the cell phone signal. It is also possible external interferences are affecting your cellular coverage. Note that cellular signals are generally radio waves and obstructed a lot as they cover long distances to reach your phone. 

Another thing that weakens the reception is internal interferences. These include such things as thick building materials like layers of brick and thick concrete, radiant barriers, glasses and metal, magnetic and electronic clutter as well as conductive materials that block or weaken an incoming coverage.

 

Introduction:
Signal Booster GW-20DWL-NH is designed to enhance and improve the quality of three band DCS 1800MHz / WCDMA 2100MHz / LTE 2600MHz connection. There're black and white colors for options. This model is enough to provide reliable coverage of signal in the area of up to 800 m². It is recommended to use in offices, apartments, houses etc.

The model is equipped with an LCD screen in a nice and symmetrical body, which displays the current level of input signal. The information on the LCD screen, greatly simplifies the process of adjusting the gain of the system. The connectors under the screws allow to build device on a wall or other vertical surface.

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.
