Coaxial adapter MikroTik CA-NM-RSF — N male to RPSMA female

The MikroTik CA-NM-RSF is a compact coaxial adapter that converts an N male connector to an RPSMA female connector. Designed for RF and antenna cabling, the adapter provides a simple mechanical and electrical interface between devices that use an N male and those that require an RPSMA male plug. Its small form factor makes it suitable for use in tight installations, test benches, and temporary connections where preserving signal continuity and connector compatibility is required.

Advantages

The adapter offers reliable mechanical conversion between connector types without requiring cable replacement or permanent modifications. Its gold- or nickel-plated contact surfaces provide stable electrical contact and corrosion resistance for typical indoor and sheltered outdoor environments. The compact construction minimizes insertion loss over short jumper lengths and keeps weight and bulk to a minimum on antenna assemblies or networking equipment.

Suitable for

• Connecting devices with N male output to antennas or cables with RPSMA male connectors
• Temporary test setups and RF measurement benches
• Field repairs or modifications of networking and wireless equipment
• Integrating small wireless modules or routers into larger antenna systems

Key specifications

• Connector conversion: N male to RPSMA female
• Application: RF/antenna cabling and connector adaptation
• Construction: compact metal body suitable for inline use
• Typical use environment: indoor and sheltered outdoor installations
• Impedance compatibility: for 50 Ω RF systems

How to use

Attach the adapter by screwing the N male side onto the corresponding N female port until fully seated and secure the RPSMA female side to the RPSMA male plug by hand, ensuring proper alignment of the center pin and threads. Avoid excessive force when tightening; hand-tight plus a small quarter-turn with an appropriate tool is sufficient. Check for stable mechanical connection and confirm RF link performance after installation. For best results, use the adapter in short jumper segments and avoid repeated heavy flexing which may wear connector surfaces.

Usage recommendations

Use this MikroTik CA-NM-RSF adapter in dry or sheltered environments and verify impedance and connector compatibility before permanent installations. When used outdoors, protect the connection from moisture with suitable weatherproofing materials and avoid placing tensile load on the adapter to prevent connector damage.
