Overview of the CAB-L400-20-TNC-N=
The CAB-L400-20-TNC-N= is a 20-meter coaxial RF cable designed for high-frequency signal transmission in Cisco wireless and industrial networks. Featuring TNC male to N male connectors, it bridges Cisco antennas, radios, or sensors to base stations, ensuring minimal signal loss in demanding environments like outdoor Wi-Fi deployments or IoT monitoring systems.
Technical Specifications and RF Performance
- Impedance: 50 Ohm for precise impedance matching, critical for reducing signal reflection.
- Frequency Range: Supports 0–6 GHz, covering most Cisco Aironet and industrial RF applications.
- Shielding: Double-braided shield with 95% coverage to block EMI from motors or power lines.
- Durability: IP67-rated connectors for waterproof/dustproof performance in harsh outdoor conditions.
- Cable Type: Low-loss LMR-400 equivalent (attenuation: ~4.8 dB/100m at 2.5 GHz).
Key Applications in Cisco Ecosystems
- Wireless Networks: Connecting Cisco Aironet 4800/3800 series access points to directional antennas.
- Industrial IoT: Linking sensors or RFID readers to Cisco industrial routers (e.g., IR1101).
- Public Safety: Backhaul for Cisco Ultra-Reliable Wireless Backhaul (URWB) systems.
Addressing Critical User Concerns
Q: Is this cable compatible with non-Cisco antennas?
Yes, but Cisco recommends using certified antennas (e.g., AIR-ANT2547V-N) to ensure optimal gain and radiation patterns.
Q: Can it handle high-power transmissions?
Rated for 150W PEP (Peak Envelope Power), the CAB-L400-20-TNC-N= suits high-output Cisco CBRS radios or private LTE setups.
Why Prioritize Cisco-Certified RF Cables?
Generic coaxial cables often suffer from impedance mismatches or shield gaps, leading to signal degradation or interference. The CAB-L400-20-TNC-N= is engineered to maintain VSWR <1.5:1 across its frequency range, ensuring reliable connectivity.

Installation and Maintenance Tips
- Bend Radius: Maintain a minimum 50mm radius to avoid kinking the dielectric core.
- Grounding: Use lightning arrestors for outdoor installations to protect against surges.
- Connector Care: Tighten TNC connectors to 12–15 in-lbs torque to prevent loosening from vibration.
Final Insight
In ruggedized deployments—like oil rigs or smart cities—cable reliability trumps cost savings. I’ve witnessed “budget” RF cables fail within months due to moisture ingress or shield corrosion, while the CAB-L400-20-TNC-N= endured years in coastal installations without degradation. For mission-critical RF links, this cable is a non-negotiable asset. Prioritize durability over upfront savings—it pays dividends in uptime.
