How It Works (System Diagram Concept):

1. Outdoor Donor Antenna: Installed on the roof or outside a window to capture the best available cellular signal.
2. Coaxial Cable: Runs from the outdoor antenna to the AYS-30-CGDWL amplifier unit (this product) located indoors.
3. Amplification: The unit amplifies the weak signal.
4. Indoor Distribution: The boosted signal is distributed via coaxial cables to 4-12 indoor antennas mounted throughout the building.
5. Improved Coverage: Strong, reliable signal is broadcast to all mobile devices within the covered area.
