Coaxial cable OEM N male to SMA male 7.5 m CF400 — 7.5 metre N‑male to SMA‑male coaxial cable, CF400

This OEM N male to SMA male coaxial cable is 7.5 metres long and built with CF400 construction to deliver a shielded RF connection between devices using N‑male and SMA‑male interfaces. The cable provides a fixed-length link suitable for outdoor and indoor installations where a robust, low-loss connection is required between antennas, radio equipment, or test instruments. Its terminated ends allow immediate use without additional adapters when connecting compatible N and SMA male ports.

Advantages

The CF400 cable construction offers consistent shielding and mechanical durability across the 7.5 m run, reducing susceptibility to interference and preserving signal integrity. Terminated N‑male and SMA‑male connectors simplify installation by removing the need for on-site crimping or soldering. The fixed-length design ensures predictable RF characteristics and easier cable management compared with loose, unbalanced assemblies.

Suitable for

• Connecting an antenna with N‑male port to equipment with an SMA‑male input
• Laboratory and test-bench RF measurements where a stable 7.5 m link is required
• Field installations requiring a durable, shielded coaxial run between radio devices
• Temporary or semi-permanent setups where quick connection and disconnection are needed

Key specifications

• Length: 7.5 metres
• Cable type: CF400 construction (foam dielectric, shielded coaxial)
• Connector A: N male
• Connector B: SMA male
• Application: RF signal transmission between N and SMA interfaces
• Shielding: Multi-layer braid/foil shield for reduced EMI
• Impedance: 50 ohm nominal

How to use

Connect the N‑male end to the corresponding N female socket and the SMA‑male end to the SMA female socket on the other device, ensuring threads are engaged cleanly and tightened by hand or with appropriate torque tools if specified by the equipment manufacturer. Route the cable to avoid sharp bends and excessive tension; maintain bending radii in line with CF400 recommendations. Verify secure connections before powering RF equipment and perform a continuity or VSWR check if precise transmission performance is required.

Usage recommendations

Avoid kinking, repeated flexing at the connector junctions, and exposure to prolonged moisture or chemical contaminants. For outdoor installations consider additional weatherproofing at connector interfaces and support the cable along its length to prevent strain on the connectors. If higher frequency performance or lower loss is required, assess suitable alternative cable constructions or shorter cable lengths.
