Coaxial cable OEM N male to SMA male 5 m CF400

Coaxial cable OEM N male to SMA male 5 m CF400 is a 5-meter RF interconnect cable constructed with CF400 low-loss coaxial material and fitted with an N-type male connector on one end and an SMA male connector on the other. It is intended for reliable transmission of RF signals between devices that use N and SMA ports, providing consistent impedance and reduced signal attenuation across the cable length. The cable's length and connector combination make it suitable for laboratory setups, antenna connections, and equipment link-ups where a durable, flexible 5 m RF lead is required.

Advantages

The CF400 low-loss construction delivers lower attenuation compared with standard coaxial leads of similar diameter, which helps preserve signal strength over the 5 m length. The robust OEM N male connector offers secure coupling and good mechanical durability for outdoor or indoor applications, while the SMA male connector provides compact termination for devices with small RF ports. The cable is flexible enough for routing in racks or test benches and is designed to maintain consistent characteristic impedance to minimise reflections and preserve measurement accuracy.

Suitable for

• Connecting antennas to routers, modems or RF front-ends with N and SMA ports
• Test bench and laboratory measurement setups requiring a 5 m RF link
• Temporary field installations and equipment interconnects where flexibility and low loss matter
• Linking signal generators, spectrum analyzers, and transceivers with mixed connector types

Key specifications

• Length: 5 meters
• Connector A: N-type male
• Connector B: SMA male
• Cable type: CF400 low-loss coaxial construction
• Impedance: 50 Ω (nominal)
• Typical application: RF signal transmission between N and SMA interfaces
• Flexibility: suitable for routing in racks and test benches

How to use

Ensure both devices are powered down or isolated as required for safe connection. Align the N male and SMA male connectors with their mating ports, hand-tighten the SMA coupling nut to the device's SMA jack, and secure the N connector by threading it to the corresponding N-type female port until fully engaged. Avoid over-tightening; use appropriate torque tools if exact torque values are required by your equipment. Route the cable to avoid sharp bends and suspension loads, and keep it clear of high-power mains wiring or sources of strong electromagnetic interference.

Usage recommendations

For best performance, minimise sharp bends (maintain bend radius recommended by the cable manufacturer), avoid repeated flexing at connector junctions, and periodically inspect connectors for corrosion or loose threads. When used in measurement setups, verify connector tightness and cable condition before critical tests to reduce measurement uncertainty.
