Antenna Waterproof Comparison Test Report

Step 1-4: Assembly

Seal connector rear with silicone and fasten securely to aluminum extrusion antennas.

Step 5-7: Isolation

Apply self-melting waterproof tape around the junction of the middle antenna for comparison.

Step 8-12: Immersion

Submerged in 50cm water for over 5 hours (15:06 to 20:06). Monitored floating status.

Step 13: Result

Disassembly verifies that internal parts remain completely dry and moisture-free.

Wrapped Antenna: Perfectly dry; absolutely no water inside.
Unwrapped Antenna: Slight water in the gasket, but no water entry into the connector.
Conclusion: FT-RF antennas maintain superior build quality; proper connector waterproofing is key.

1. Must prioritize moisture-proof isolation using waterproof or self-melting tape.

2. Beware of moisture intrusion caused by internal/external temperature differences.

3. Connectors should be completely covered to prevent static electricity damage.

4. Install lightning arresters directly at the connector to minimize wire loss.

5. Use metal rods for mounting to help release lightning energy safely.

6. Ensure aluminum extrusion part is exposed to maintain omnidirectional characteristics.

7. Use low-loss coaxial cables and keep them as short as possible.

8. Lock connectors tightly but avoid excessive tool force to prevent damage.

9. Lightning arresters must also follow strict waterproof/moisture-proof methods.

10. Attention to these small details makes everyone a professional installer.
