3. Broadcast: The powerful, cleaned-up signal is broadcast indoors through the connected indoor antenna(s), creating a strong personal cell zone.

Ideal For:

• Homes in rural areas, basements, or with metal/energy-efficient construction.
• Office buildings, warehouses, and workshops with poor signal penetration.
• Small businesses like cafes, restaurants, and stores wanting to improve customer and staff connectivity.
