Product Description
ATNJ Tri-Band 2G 3G 4G Mobile Signal Booster
The ATNJ Tri-Band Signal Booster is a professional-grade cellular amplification system designed to enhance 2G, 3G, and 4G signals in areas with weak network coverage. This 80dB gain repeater operates across 900MHz, 1800MHz, and 2100MHz frequency bands to provide reliable voice calls and data connectivity.
How It Works
The system captures weak cellular signals through an outdoor antenna, amplifies them using sophisticated circuitry, and rebroadcasts the enhanced signal indoors through an indoor antenna unit.
