4. Setup Guide
Proper installation is crucial for the optimal performance of your signal booster. Follow these steps carefully:
4.1. Pre-Installation Check: Choosing the Right Booster
Before installing, ensure you have at least 1-2 bars of outdoor signal at the location where you plan to install the outdoor antenna. You can check your current signal strength using your phone:
- For iOS: Dial *3001#12345#* and press call. Navigate to 'Serving Cell Info' and check 'Freq Band Indicator'.
- For Android: Download an app like 'LTE Discovery'. Press 'SIGNALS' and check 'Band Number'.
*Note: Turn off Wi-Fi to display the network type at the top of the screen. If it shows "0" or "Unkown", test more times outside at the strongest signal position.*
4.2. Installation Steps
- Step 1: Position the Outdoor Antenna. Search for a location where you can receive a good signal (stronger than -70dB). Install the outdoor Yagi antenna at this location, pointing it towards the nearest base station or cell tower. Ensure the outdoor antenna is placed where it can receive a good signal.
- Step 2: Connect Antennas to Booster. Use the provided coaxial cable to connect the outdoor antenna to the "BTS" port of the signal booster. Connect the indoor ceiling antenna to the "MS" port of the signal booster. Ensure all connections are tightened securely.
- Step 3: Power On and Check Signal. After all connections are made and secured, connect the power adapter to the booster and plug it into an electrical outlet. Turn on the power. Check your mobile phone signal strength to verify the improvement.
*Note: The two antennas need to be separated by a brick wall, and the distance between them should be more than 33ft (10m) to prevent interference.*
5. Operating Instructions
Once installed and powered on, the GOBOOST signal booster operates automatically. The intelligent LED display provides real-time feedback on its status.
5.1. LED Display Interpretation
The booster features five intelligent LCD screens, one for each frequency band. These displays indicate:
- Frequency Band: Clearly shows which band (e.g., 800MHz (B20), 900MHz (B8), 1800MHz (B3), 2100MHz (B1), 2600MHz (B7)) is being boosted.
- Signal Strength: Displays the signal strength graphically and numerically, providing detailed and clear information to the user.
- Output Power: Shows the output power for each band.
5.2. Automatic Gain Control (AGC)
The integrated AGC chip intelligently controls each band, preventing interference with base stations and extending the equipment's lifespan. This feature ensures stable and efficient signal amplification without manual adjustment.
6. Maintenance
To ensure the longevity and optimal performance of your GOBOOST signal booster, follow these maintenance guidelines:
- Cleaning: Keep the booster unit and antennas clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or aerosols.
- Ventilation: Ensure the booster unit has adequate ventilation. The strip design on the back helps dissipate heat, so avoid blocking the space between the booster and walls.
- Cable Connections: Periodically check all coaxial cable connections to ensure they are tight and free from corrosion. Loose connections can degrade signal quality.
- Environmental Conditions: Avoid exposing the booster unit to extreme temperatures, direct sunlight, or high humidity.
- Power Supply: Use only the original 5V, 3A power adapter provided with the unit.
7. Troubleshooting
If you experience issues with your signal booster, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No signal improvement |
|
|
| Signal bars fluctuate or drop |
|
|
| Booster unit is hot |
|
|
| LED display shows no activity |
|
|
8. User Tips
Here are some additional tips to maximize your signal booster's effectiveness:
- Optimal Antenna Placement: Experiment with the exact positioning and direction of the outdoor antenna. Even small adjustments can significantly impact performance.
- Maximize Separation: The greater the physical separation (and presence of solid barriers like walls) between the outdoor and indoor antennas, the better. This prevents signal feedback (oscillation) which can reduce efficiency.
- Cable Management: Route cables neatly and securely to prevent damage and maintain signal integrity. Avoid sharp bends or kinks in the coaxial cable.
- Power Cycle: If you notice a sudden drop in performance, try power cycling the booster (unplug, wait 30 seconds, plug back in).
- Check Local Regulations: Ensure the use of a signal booster complies with local telecommunication regulations in your area.
