Coaxial cable OEM N male to SMA male 2.5 m CF400 — low-loss RF jumper

Straight coaxial RF cable with an OEM N male connector on one end and an SMA male connector on the other, 2.5 m in length. Constructed with CF400 low-loss coaxial cable, this RF jumper is designed to provide stable signal transmission and reliable impedance matching when connecting RF equipment, antennas, test instruments and wireless devices. The cable combines a robust outer jacket with precision connectors to minimise attenuation over the run while maintaining mechanical flexibility for typical installation environments.

Advantages

The CF400 low-loss dielectric and conductor geometry reduce insertion loss across a wide frequency range, improving overall signal integrity compared with standard coax. Precision N male and SMA male connectors provide secure, low-reflection connections with consistent characteristic impedance. The 2.5 m length balances reach and loss for many bench and field setups, while the cable assembly’s mechanical construction resists deformation and preserves connector alignment during handling and installation.

Suitable for

• Connecting RF test equipment to antennas or measurement devices
• Interfacing wireless devices, routers or base stations with external antennas
• Laboratory and bench-top RF experiments and prototyping
• Field installations requiring N-to-SMA transition with low insertion loss

How to use

Align the N male and SMA male connectors with the corresponding female ports on the devices to be connected. Hand-tighten the SMA male coupling nut until secure and use appropriate torque for the N connector where required by the equipment manufacturer; avoid over-tightening to prevent damage to connector threads. Route the cable to minimise sharp bends and keep it clear of high-EMI sources. For best performance, maintain gentle bend radii consistent with the cable’s flexibility and avoid kinking.

Usage recommendations

Inspect connectors before use to ensure clean contact surfaces; clean with a suitable, lint-free wipe if contamination is present. For long-term installations, periodically check connector tightness and cable condition. When higher frequencies or the lowest possible attenuation are required, verify that the CF400 cable characteristics meet the application’s frequency band and loss budget.
