3. Instalasi jeung Setup

Follow these steps to install your GOBOOST Car Signal Booster:

1. Mount the Car Antenna: Securely attach the Car Antenna (external antenna) to the exterior of your vehicle, typically on the roof or trunk, ensuring it has a clear line of sight to cell towers.
2. Jalur kabel: Carefully route the 2M cable from the Car Antenna into the vehicle's interior to the location where the Signal Booster will be placed.
3. Connect External Antenna: Connect the routed cable from the Car Antenna to the 'BTS' port on the Signal Booster using the NK-FJ Connector if necessary.
4. Connect Internal Antenna: Attach the Whip Antenna (internal antenna) to the 'MS' port on the Signal Booster. Position the Whip Antenna inside the vehicle where you need improved signal, ensuring it is not too close to the external antenna to prevent oscillation.
5. Daya Hurung: Plug the Car Power Plug into your vehicle's 12V power outlet and connect the other end to the Signal Booster's power input. The booster will power on automatically.

4. Parentah Operasi

Once installed and powered on, the GOBOOST Signal Booster will automatically begin to amplify the cellular signal. Observe the display for real-time signal strength information.

Signal Strength Display:

The booster features a unique numerical display that shows the signal strength for each channel (CH1, CH2, CH3) in dB and dBm, providing accurate feedback on the booster's performance.

How the Booster Works:

1. Receives Signal: The external Car Antenna captures weak cellular signals from the nearest cell tower.
2. Boosts Signal: The Signal Booster amplifies the received signal.
3. Broadcasts Signal: The internal Whip Antenna broadcasts the amplified signal within your vehicle, providing improved reception to your mobile devices. Simultaneously, your device's outgoing signals are captured by the Whip Antenna, amplified by the booster, and sent back to the cell tower via the Car Antenna.
