ALC MGC AGC Cell Phone Signal Amplifier Dual Band 900MHz 1800MHz
Dual Band Cell Phone Signal Amplifier 2G 4G 900 / 1800MHz Cellular Repeater Booster
Selling Point
Latest generation LCD amplifier is used to amplify weak GSM signals on two different frequencies. The LCD screen displays signal strength, setup advice, error messages, power and ALC data. In addition, the signal booster has another port for additional internal antenna, allowing the user to evenly redistribute the amplified signal.
This model guarantees effective reinforcement in medium-sized homes and offices, shops and other properties up to 300 m² (3200 ft²).
The device amplifies GSM signals simultaneously on 900 and 1800 MHz. 900 MHz is the most common GSM signal transmission frequency in the European Union and around the world. 1800 MHz is mainly used as a complementary frequency to 900 MHz, and in some regions as the main frequency. Therefore, the dual-band amplifier is suitable for users of mobile operators operating on different frequencies.

How does it work?
1. RECEIVES SIGNAL
The powerful antenna reaches out to access a good signal, and delivers it to the booster.
2. BOOSTS SIGNAL
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3. BROADCASTS SIGNAL
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
Product Description
2G 4G signal booster (B3+B8)
Gain : 70db
Max power : 20dbm
ALC functon
The ALC function can prevent excessive signal output and cause interference.
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.
Packaging Including:

2. Power adapter
3. Outdoor Log-periodic antenna
4. Indoor Omni antenna and Ceiling antenna
5. 5 meters cable
6. 20 meters cable
