2G 4G Dual Band Signal Booster E900/1800MHz Cell Phone Signal Repeater Amplifier

Check the frequency range before you buy

To make sure that the amplifier you buy is suitable for your mobile operator, please follow the steps and detect the frequency range of your mobile phone. This signal booster can only work on Band 8, Band 3.

Band 8 = B8 = 2G GSM900/EGSM900
Band 3 = B3 = 4G LTE1800/4G LTE1800
Band 1 = B1 = 3G WCDMA2100/3G UMTS2100

Product Description

LCD Display

Even a non-technical person can easily install and use this signal booster. The display shows all important information and prompts: input and output signal strength, installation details, power, AGC (automatic gain control), etc.

AGC MGC Function

The AGC and MGC functions can prevent the amplified signal from causing interference to the base station. Even if it is installed incorrectly, the amplifier can protect the normal operation of the base station.

Adjustable Gain

Automatic adjust the system gain to avoid the repeater self-excitation

2G 4G Dual Band Signal Booster

Accessories

a. One dual band signal booster;

b. One indoor antenna;

c. One outdoor antenna;

d. 20meter cable and 5meter cable;

e. User manual;

f. Power adapter.

2G 4G Dual Band Signal Booster

Installation Approaches

1.Fix up outdoor antenna reception on housetop and point to signal tower;

2.Connect outdoor antenna to “outdoor” port in repeater nachine through cable;

3.Connect indoor antenna(s) to “indoor” port in repeater machinethrough cable also;

4.Plug power adaptor into AC power socket and finish installation.

2G 4G Dual Band Signal Booster

The repeater makes the signal stronger in places with poor signal coverage such as:

1) Underground areas: basements, parking lots, tunnels;

2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;

3) Places distant from the BTS like private houses.
