- Outdoor Antenna Placement: Mount the outdoor directional antenna in a location with the strongest available cellular signal. Use the Signal Supervisor App to assist in finding the best direction and signal strength.
- Col·locació de l'antena interior: Install the two indoor panel antennas in areas where signal improvement is desired. Ensure sufficient separation between the outdoor and indoor antennas to prevent oscillation.
- Connexió per cable: Connect the outdoor antenna to the booster unit using the provided 400 coaxial cable. Connect the indoor antennas to the booster unit. Window wire can be used for connections without drilling.
- Encès: Connect the power adapter to the booster unit and plug it into a power outlet.
- Configuració de l'aplicació: Download and use the HiBoost Signal Supervisor App for fine-tuning and monitoring. The app helps adjust output and displays signal strength.

The HiBoost Signal Supervisor App offers multiple functionalities to assist with installation, including video guides, remote monitoring, a signal dashboard, and direct access to customer support.
4. Instruccions de funcionament
Once installed, the HiBoost 15K 2.0 SL Booster operates automatically to enhance cellular signals. The booster is compatible with all major U.S. carriers and supports 4G LTE and 5G in existing 4G bands via Dynamic Spectrum Sharing (DSS).
Característiques operatives clau:
- Control automàtic de guany (AGC): The booster intelligently detects and adjusts signal strength for optimal performance, preventing overload and oscillation.
- Pantalla LCD: The integrated LCD screen provides real-time information on signal status and performance, allowing for manual adjustments if needed.
- Signal Supervisor App: Use the app for remote monitoring of the booster's status, signal metrics, and to fine-tune settings from your smartphone.
