Detailed Product Description

850MHz 1700MHz Dual Band Signal Booster ALC Automatic Level Control

850 1700 Dual Band Signal Booster 2G 3G 4G Mobile Phone Signal Repeater Amplifier

Selling Point

1. Smart LCD: Show the real-time signal strength.

2. Sleeping Mode : When no user calls, the device works in Sleeping mode, so as to achieve the purpose of energy saving.

3. ALC(Automatic Level Control) : Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling and data transfer quality.

4. AGC (Automatic Gain Control) : When the downlink output signal is too strong or self-oscillated, booster can automatically reduce the gain and reduce the interference signal.

5. MGC (Manual Gain Control) : In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-27dB.
