Product Features

Tri-Band Signal Amplification for Comprehensive Coverage

Boost connectivity across the most essential cellular networks. The amplifier enhances signals for 2G voice (900/1800 MHz), 3G data/voice (2100 MHz), and 4G LTE data (800/1800/2600 MHz), ensuring support for calls, texts, and high-speed internet on all major carriers.

Dramatically Enhanced Call Quality and Data Speeds

Experience up to 32 times stronger signal strength. This results in a 98% reduction in dropped calls and mobile data speed improvements of up to 4 times, enabling clear conversations, smooth video streaming, and faster web browsing.

Universal Compatibility with All Major Carriers

Use with any GSM-based mobile network and device. The booster works seamlessly with all major service providers and supports any smartphone, tablet, or cellular modem, enhancing both voice and data services.

Extended Mobile Device Battery Life

Reduce the power drain on your phone. By providing a strong local signal, your mobile devices no longer need to amplify their own transmission power, which can significantly extend battery life during use.

Automatic Gain Control for Stable Operation

Ensure optimal performance without manual adjustment. The built-in Automatic Gain Control (AGC) intelligently adjusts the amplifier’s power to deliver the strongest possible signal while preventing system oscillation and network interference.

Professional Installation Kit Included

Get everything needed for setup in one box. The package includes a weather-resistant outdoor antenna, an indoor antenna, the main amplifier unit, coaxial cables, mounting hardware, a power adapter, and a detailed installation guide.

Certified Safety and Reliability

Operate with confidence thanks to rigorous testing. The device is CE and FCC certified, comes with a 2-year warranty, and is backed by dedicated local technical support for peace of mind.

Easy Monitoring with LED Status Indicators

Quickly diagnose system health. LED indicators on the main unit provide clear visual feedback on power, signal strength, and potential errors, simplifying setup and troubleshooting.
