5. Setup Instructions
Proper installation is crucial for optimal performance. Follow these steps carefully.
5.1 Choose an Installation Location
Select an outdoor location that is as high as possible and free from obstructions (e.g., buildings, trees) to ensure a clear line of sight to cellular towers. The antenna is omni-directional, meaning it receives signals from all directions, but height and clear surroundings are still beneficial.

5.2 Assemble the Antenna and Mounting Hardware
- Attach the provided mounting bracket to the base of the antenna using the small bolts and nuts.
- Secure the U-bolts to the mounting bracket.
- Mount the assembled antenna onto a pole (40-60mm diameter recommended) using the U-bolts, washers, and nuts. Ensure it is tightened securely to withstand wind.

5.3 Connect the Cables
- Connect one end of the 10-meter RG58 cable to the N Female connector at the base of the antenna.
- Route the cable to your router or signal booster, ensuring it is protected from damage and moisture.
- Depending on your device's input, use the appropriate adapter (TS-9 or N male) to connect the other end of the RG58 cable to your router or signal booster. Ensure all connections are finger-tight.

6. Operating Instructions
Once the antenna is installed and connected, ensure your router or signal booster is powered on. The antenna will automatically begin receiving and transmitting signals. No specific configuration is required for the antenna itself.
- Signal Strength Monitoring: Check the signal strength indicator on your connected device (router, signal booster, or phone) to verify improved reception.
- Optimal Placement: While omni-directional, slight adjustments to the antenna's height or immediate surroundings might further optimize signal quality in some challenging environments.
7. Maintenance
The SIGNALPLUS antenna is designed for durability and requires minimal maintenance.
- Periodic Inspection: Annually inspect the antenna and mounting hardware for any signs of wear, corrosion, or loosening. Ensure all connections remain tight.
- Cleaning: If necessary, gently clean the antenna's radome with a soft, damp cloth to remove dirt or debris that might accumulate over time. Avoid harsh chemicals or abrasive materials.
- Cable Integrity: Check the coaxial cable for any kinks, cuts, or damage. Damaged cables can degrade signal performance.
8. Troubleshooting
If you experience issues with your antenna, consider the following troubleshooting steps:
- No Signal Improvement:
- Ensure all cable connections are secure and correctly attached to both the antenna and your device.
- Verify that your router or signal booster is powered on and configured correctly according to its own manual.
- Check for any new obstructions that might be blocking the signal path.
- Confirm that the antenna is mounted at a sufficient height.
- Intermittent Signal:
- Inspect the coaxial cable for damage or loose connections.
- Ensure the mounting hardware is firmly secured and the antenna is not swaying in the wind.
- Physical Damage:
- If the antenna or cables are visibly damaged, they may need replacement.
If problems persist after following these steps, please contact SIGNALPLUS customer support.
