How to use
Ensure both mating connectors are clean and free of debris before hand-tightening the N connectors. Align the N-male and N-female threads and turn by hand; finish securing with a torque wrench if specified by your equipment manufacturer to avoid over-tightening. Route the cable to avoid sharp bends and mechanical strain; allow gradual curves with radius suitable for LMR-400 to maintain electrical performance.

Usage recommendations
For best long-term performance, avoid repeated flexing near the connectors, use proper weatherproofing at outdoor terminations, and follow equipment manufacturer torque specifications when tightening N connectors.
