How the Signal Booster Works

The Signal Booster uses an external aerial antenna to capture existing weak signals from the cell tower. The amplifier then boosts this signal to full strength and transmits it through the internal antenna, which distributes the enhanced signal throughout the coverage area.

Installation is straightforward and typically takes only a few minutes. Follow our step-by-step installation guide for detailed instructions.
