3. Setup Instructions
Proper installation is crucial for optimal performance of your GOBOOST cellular amplifier. Follow these steps carefully:
- Identify Signal Weakness: Determine the area where you experience weak signal. This is where the indoor antenna will be placed.
- Outdoor Antenna Placement:
Install the outdoor antenna in a location with the strongest possible signal from your cellular provider's tower. This is typically on a rooftop or high pole. Ensure the outdoor antenna is pointed towards the nearest cell tower.
NOTE: The outdoor and indoor antennas must be separated by a brick wall or similar obstruction, and maintain a minimum distance of 10 meters (approximately 33 feet) to prevent interference.
- Connect Outdoor Antenna: Connect the outdoor antenna cable to the "BTS" port on the signal booster.
- Indoor Antenna Placement:
Install the indoor antenna in the area where you want to improve signal coverage. Ensure it is not facing the outdoor antenna directly.
- Connect Indoor Antenna: Connect the indoor antenna cable to the "MS" port on the signal booster.
- Power Connection: Connect the power adapter to the signal booster and then plug it into a power outlet.
- Verify Installation:
Once powered on, observe the LED display on the booster. It will show signal strength and output power for each band. A stable and strong signal indication means the installation is successful.

4. Operating Instructions
The GOBOOST 5G Cellular Amplifier operates automatically once properly installed and powered on. It continuously monitors and amplifies cellular signals.
- Automatic Gain Control (AGC): The booster is equipped with an AGC chip that automatically adjusts the gain to prevent interference with the base station, ensuring stable and reliable signal amplification.
- LED Display: The integrated LED display provides real-time information on signal strength and output power for each of the five frequency bands. This allows for easy monitoring of the booster's performance.

5. Maintenance
The GOBOOST cellular amplifier requires minimal maintenance. Follow these guidelines to ensure longevity and optimal performance:
- Cleaning: Keep the booster unit and antennas clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ventilation: Ensure the booster unit has adequate ventilation. The strip design on the back is intended to dissipate heat; do not block these vents or mount the unit flush against a wall without proper spacing.
- Cable Integrity: Periodically check all cable connections for tightness and ensure cables are not damaged or kinked.
- Environmental Protection: Ensure outdoor antennas are securely mounted and protected from harsh weather conditions.

6. Troubleshooting
If you encounter issues with your signal booster, refer to the following troubleshooting steps:
- No Signal Receipt After Activation:
- Verify that your signal frequency matches the booster's supported bands. The device only amplifies corresponding frequencies.
- Check if the outdoor antenna is correctly pointed towards the nearest cellular signal tower.
- Ensure the location where the outdoor antenna is installed has a strong existing signal.
- Unstable Signal Strength:
- Ensure there is maximum possible distance between the outdoor and indoor antennas.
- Confirm that a physical barrier (e.g., a brick wall) separates the outdoor and indoor antennas.
- Make sure the antennas are not installed on the same horizontal plane.
- General Issues:
- If the problem persists, provide video or pictures to customer support to illustrate the exact issue.
- Listen to suggestions from customer support for installation adjustments.

9. User Tips
- Frequency Compatibility: Before purchasing or installing, always confirm that the booster's supported frequency bands (800, 900, 1800, 2100, 2600 MHz) match those used by your local cellular providers. For example, if you are in Egypt, ensure these bands are compatible with local networks.
- Optimal Antenna Separation: Maintaining a significant physical separation (at least 10 meters) and a physical barrier (like a brick wall) between the outdoor and indoor antennas is critical to prevent oscillation and ensure efficient signal boosting.
- Outdoor Signal Strength: The booster amplifies an existing signal. If there is no signal outdoors, the booster cannot create one. Ensure the outdoor antenna is placed where a usable signal is present.
- Placement for Coverage: Consider the layout of your space when placing the indoor antenna to maximize coverage. For multi-story buildings, a ceiling antenna might be more effective than a panel or table antenna.
