4. Setup and Installation
Proper installation of the interior patch antenna is crucial for optimal performance of your cell phone signal booster system.
- Antenna Placement: Identify a location inside your vehicle or RV where you typically use your cellular device. The patch antenna should be placed as close as possible to this area, ideally on a dashboard, console, or window, facing the direction where you need signal coverage. Ensure the antenna is not obstructed by metal objects.
- Cable Routing: Carefully route the attached 10 ft. cable from the antenna to the location of your SureCall signal booster. Avoid kinking, pinching, or sharply bending the cable. Secure the cable using cable ties or clips to prevent interference with vehicle operation.
- Connect to Booster: Connect the FME-Female connector of the patch antenna cable to the designated interior antenna port on your SureCall signal booster. Ensure the connection is hand-tightened securely.
- Power On Booster: Once all connections are made, power on your SureCall signal booster according to its specific instruction manual.
Note: For detailed installation instructions specific to your SureCall signal booster model, please refer to its accompanying user manual.
5. Operation
The SureCall SC-110W interior patch antenna operates passively in conjunction with a compatible SureCall cell phone signal booster. Once the booster system is fully installed and powered on, the antenna will receive amplified cellular signals from the booster and distribute them within the vehicle's interior. Your cellular device should automatically detect the improved signal strength.
For optimal performance, ensure that your cellular device is within the effective coverage area of the interior patch antenna. The effective range can vary based on the booster's power, vehicle interior, and external signal conditions.
6. Maintenance
The SureCall SC-110W antenna requires minimal maintenance.
- Cleaning: Periodically wipe the antenna surface with a soft, dry cloth to remove dust or debris. Do not use harsh chemicals or abrasive cleaners.
- Cable Inspection: Regularly inspect the antenna cable for any signs of damage, such as cuts, kinks, or frayed insulation. Damaged cables can impair performance.
- Environmental Conditions: Ensure the antenna is not exposed to extreme temperatures or direct moisture, which could affect its longevity and performance.
There are no user-serviceable parts inside the antenna. Any repairs should be performed by qualified personnel.
7. Troubleshooting
If you experience issues with your signal booster system, consider the following troubleshooting steps related to the interior patch antenna:
- No Signal Improvement:
- Verify that the FME-Female connector is securely attached to the interior antenna port on your signal booster.
- Ensure the antenna is positioned correctly within the vehicle, facing the area where signal improvement is desired.
- Check for any obstructions between the antenna and your cellular device.
- Confirm that the signal booster itself is powered on and functioning correctly (refer to the booster's manual).
- Weak Signal Improvement:
- Try repositioning the interior patch antenna to a different location within the vehicle to find an optimal spot.
- Ensure the exterior antenna (if applicable) is properly installed and receiving a strong outside signal.
