Coaxial Adapter MikroTik CA-NF-SF — N Female to SMA Female coax adapter

The MikroTik CA-NF-SF is a compact coaxial adapter that converts an N female connector to an SMA female connector. It provides a passive, mechanical connection between devices or cables that use N-type and SMA-type RF interfaces, maintaining signal continuity without active electronics. The adapter is intended for use in installations, temporary connections, and testing where connector compatibility is required between antennas, radios, or coaxial cables.

Advantages

The adapter offers a simple, low-profile solution for connecting N female to SMA female interfaces without modifying existing cabling. Its passive design ensures no power or signal amplification is introduced, preserving the original signal characteristics. The compact size makes it convenient for use in tight spaces or for temporary test setups where easy interchangeability is needed.

Suitable for

• Connecting equipment with N female connectors to devices or antennas with SMA female connectors
• Temporary test and measurement setups in RF laboratories or fieldwork
• On-site installations where connector conversion is required to complete a link
• Adapters between different coaxial cable assemblies during troubleshooting

Key specifications

• Connector 1 type: N female
• Connector 2 type: SMA female
• Passive, no active components
• Compact mechanical design suitable for tight spaces

How to use

Align the N male connector of the cable or device with the N female side of the adapter and secure the connection by tightening the N coupling nut by hand and, if necessary, with a suitable wrench to a light torque to ensure a stable mechanical connection. Align the SMA male connector with the SMA female side of the adapter and carefully screw it in place, ensuring proper thread engagement without cross-threading. Use the adapter only as an interconnection; avoid excessive bending or mechanical stress on the connectors to prevent damage.

Usage recommendations

For reliable RF performance, use the adapter in applications where impedance matching and cable attenuation have already been considered. Avoid exposing the adapter to prolonged moisture or corrosive environments; if used outdoors, protect the connection with appropriate weatherproofing materials. Inspect connectors for dirt or debris before mating and tighten connections to secure but moderate torque to prevent damage to threads.
