1. Introducció i finalview
The GOBOOST GB23-LTE-B20 Signal Booster is designed to enhance 4G LTE 800MHz (Band 20) mobile network signals, improving call quality and data speeds (uploads and downloads) in areas with weak coverage. This device helps reduce dropped calls and provides a more stable mobile connection for both home and office environments. It features an LCD display to clearly show its working status and is built with an aluminum alloy shell for efficient heat dissipation and extended service life.
Nota important:
- This booster specifically supports the 800MHz (Band 20) frequency. Ensure your mobile carrier uses this frequency in your area.
- For optimal performance, there must be an existing outdoor mobile signal of at least 3 bars or more at the location where the outdoor antenna will be installed. The device cannot create a signal where none exists.

4. Configuració i instal·lació
Proper installation is crucial for the optimal performance of your signal booster. Follow these steps carefully:
4.1 Comprovació prèvia a la instal·lació
- Verify Frequency: Confirm that your mobile carrier uses the 800MHz (Band 20) frequency in your area. This booster will not work with other frequencies.
- Check Outdoor Signal Strength: Use your mobile phone to find the location with the strongest outdoor signal. You need at least 3 bars of stable signal for the booster to function effectively.
4.2 Identificació de components
4.3 Passos d'instal·lació
- Install Outdoor Antenna (Yagi Antenna):
Mount the Yagi antenna in the outdoor location where you detected the strongest signal. Point the antenna towards the nearest mobile signal tower. Ensure it is securely fixed and has a clear line of sight to the tower if possible.
Figure 5: Step 1 - Finding the strongest outdoor signal and installing the Yagi antenna. - Connect Outdoor Antenna to Booster:
Connect one end of the coaxial cable to the outdoor Yagi antenna (NJ-FK Connect) and the other end to the "Outdoor Port" (F-Female Connector) on the GOBOOST Signal Booster.
Figure 6: Step 2 - Connecting the outdoor antenna to the booster. - Install Indoor Antenna (Whip Antenna):
Install the indoor whip antenna inside your building, in the area where you want to improve signal coverage. Ensure it is positioned away from the outdoor antenna to prevent signal interference (feedback loop).
- Connect Indoor Antenna to Booster:
Connect the indoor whip antenna to the "Indoor Port" (SMA-Female Connector) on the GOBOOST Signal Booster.
Figure 7: Step 3 - Connecting the indoor antenna to the booster. - Ensure Antenna Separation:
It is critical to maintain maximum possible distance between the outdoor and indoor antennas. There should be a physical barrier (like a wall or ceiling) between them, and they should not be on the same horizontal line. This prevents the indoor antenna from feeding signal back into the outdoor antenna, which can cause oscillation and reduce performance.

Connect the power adapter to the GOBOOST Signal Booster and then plug it into a suitable electrical outlet. The device will power on automatically.

5. Instruccions de funcionament
Once all components are correctly connected and the power is supplied, the GOBOOST Signal Booster will begin operating automatically. The LCD display on the booster provides real-time information about its status.
- Encès: The booster automatically powers on when connected to an electrical outlet.
- Pantalla LCD del monitor: The LCD screen will show the current gain and output power, indicating that the device is actively boosting the signal. Observe the display to ensure it is functioning as expected.
- Check Mobile Signal: After installation, check your mobile phone's signal strength in the indoor coverage area. You should observe a significant improvement in signal bars and network performance.
6. Manteniment
The GOBOOST Signal Booster is designed for low maintenance. Follow these general guidelines to ensure its longevity and optimal performance:
- Mantenir les connexions segures: Periodically check all cable connections (outdoor antenna to booster, indoor antenna to booster, power adapter) to ensure they are tight and secure. Loose connections can degrade performance.
- Col·locació de l'antena: Ensure both outdoor and indoor antennas remain free from obstructions (e.g., new buildings, trees, furniture) that could block signals.
- Neteja: Keep the booster unit and antennas clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Dissipació de calor: The aluminum alloy shell is designed for efficient heat dissipation. Ensure the booster unit has adequate ventilation and is not placed in an enclosed space that could trap heat.
7. Solució De Problemes
If you experience issues with your signal booster, refer to the following troubleshooting guide:
| Problema | Causa possible | Solució |
|---|---|---|
| No signal improvement or "No Signal" on display |
|
|
| Signal strength is not steady or fluctuates |
|
|
| Booster not powering on |

8. Consells d'usuari
Based on common inquiries and user experiences, here are some additional tips for getting the most out of your GOBOOST Signal Booster:
- Frequency Verification is Key: Abans de la compraasing or installing, always double-check that your local mobile network operates on the 800MHz (Band 20) frequency. This is the most common reason for a booster not working.
- Outdoor Signal Strength: El reforç amplifies an existing signal. If the outdoor signal is too weak (e.g., 1-2 bars or none), the booster will have little to nothing to amplify, and performance will be poor. Aim for at least 3 stable bars outdoors.
- Antenna Isolation: The distance and physical barrier between the outdoor and indoor antennas are paramount. Insufficient separation leads to signal feedback, which can cause the booster to oscillate or shut down to protect itself.
- Col·locació òptima: Experiment with the exact placement and orientation of your outdoor antenna. Even small adjustments can sometimes lead to significant improvements in signal strength.
