How to install CAB-NM/F-LL-40F

• Plan the route: Before installation, map the run to minimize sharp bends and compression. Avoid tight radii and repeated flexing that can degrade the cable over time.
• Prepare the run: Cut to length using proper coaxial cable tools, ensuring a clean, square end. Use a suitable stripper and cutter to protect the center conductor and shielding.
• Attach connectors: Terminate the LMR-400 with N-Type male and N-Type female connectors using the recommended torque and crimping procedure. Inspect each connection for uniformity and a snug RF seal.
• Seal and protect: For outdoor segments, apply weatherproof boots, gaskets, or sealant as appropriate to shield connectors from moisture, UV exposure, and dust. Route through weatherproof conduits when required.
• Test and verify: Perform a continuity and return loss check with a suitable RF test instrument. Look for clean S11/return loss readings and confirm there are no open or shorted connections along the run.
