2G 4G 900MHz 1800MHz Dual Band Repeater GSM LTE Cellular Amplifier
2G 4G 900 / 1800MHz Dual Band Repeater Signal Booster GSM LTE Cellular Amplifier
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.
