4.2 Mounting Instructions

The antenna is designed for outdoor roof mounting. It requires a hole for cable routing and a secure fastening mechanism.

1. Prepare Mounting Surface: Choose a flat, stable surface on your vehicle or structure for mounting.
2. Drill Hole: Drill a hole with a diameter of 0.98 inches (25mm) at the chosen location.
3. Attach Adhesive: If not pre-applied, attach the 3M double-sided tape to the base of the antenna for initial positioning and sealing.
4. Insert Antenna: Pass the antenna's threaded shaft and cables through the drilled hole.
5. Secure Antenna: From the underside of the mounting surface, thread and tighten the included nut onto the antenna's shaft until secure. Ensure a tight seal to maintain IP67 rating.

7. Troubleshooting

If you encounter issues with your antenna, consider the following troubleshooting steps:

• No Signal or Weak Signal:
  • Ensure all antenna connectors (SMA for 4G LTE, RP-SMA for Wi-Fi) are securely fastened to the correct ports on your router.
  • Verify that the antenna is mounted in an optimal location, free from obstructions that could block signals.
  • Check your router's settings to confirm that external antennas are enabled, if applicable.
  • Test with another compatible router or antenna if possible, to isolate the issue.
• Intermittent Connectivity:
  • Inspect cables for any signs of damage or wear.
  • Ensure the mounting is stable and the antenna is not moving, which could affect signal consistency.
  • Check for potential sources of interference near the antenna or router.
• Physical Damage:
  • If the antenna or cables are physically damaged, contact LINOVISION support for assistance.
