How It Works:

1. The outdoor antenna captures the existing mobile signal.
2. The signal is sent via cable to the S4B20GDW-Y amplifier unit.
3. The amplifier powerfully boosts the signal.
4. The indoor antenna rebroadcasts the strong, clean signal throughout your property.

Important Installation Note: For optimal performance and to comply with ACMA rules, the outdoor and indoor antennas must be placed with sufficient separation (typically >10-15 meters). This prevents oscillation and ensures stable operation.
