Barrel Adapter Alfa Network ASP-NF-NM — N Female to N Male coaxial connector

The Alfa Network ASP-NF-NM barrel adapter converts an N female connector to an N male connector, allowing two N-type terminated coaxial components to be joined or adapted. It is intended for RF signal connections in wireless networking, antenna installations and measurement setups where matching N-type terminations are required. The adapter is made from metal with threaded coupling to provide a solid mechanical joint and consistent electrical contact between cables, antennas or test equipment.

Advantages

This adapter provides a straightforward and compact solution for converting an N female interface to an N male interface without changing cables. Its threaded N-type coupling ensures a mechanically robust connection with reliable RF continuity and reduced risk of accidental disconnection. The metal construction offers mechanical durability and good shielding for RF signals, while the small form factor keeps inline signal path length minimal.

Suitable for

• Joining two N-type coaxial cables
• Connecting N-type terminated antennas to equipment with the opposite gender
• Temporary or permanent RF test and measurement setups
• Wireless networking installations requiring adapterized terminations

When it may not be suitable

This barrel adapter is intended for N-type RF terminations only and will not convert to other connector standards without additional adapters. It is not intended to provide waterproof or weatherproof sealing by itself; exposed outdoor installations may require additional sealing or protective enclosures. The device does not change impedance — it assumes the connected components share compatible impedance characteristics.

Key specifications

• Connector conversion: N female to N male
• Connector type: N-type threaded coaxial
• Material: metal body for mechanical strength and shielding
• Coupling: threaded screw-on coupling for secure connection
• Intended use: RF signal connections for wireless networking, antennas and test equipment

How to use

Align the adapter’s N male end with the N female receptacle of the cable or device and engage the threaded coupling by hand, turning until finger-tight. Then align the adapter’s N female end with the N male connector to be joined and screw on until secure. Use appropriate torque where specified by connected equipment manufacturers to avoid over-tightening. For outdoor or high-vibration environments, consider using thread sealant or a protective boot as needed to protect the connection.

What to consider before purchase

• Confirm both mating connectors are N-type and require gender conversion from female to male
• Verify impedance compatibility with your RF system (typical N-type usage is 50 ohm)
• Consider environmental exposure and whether additional sealing or protective hardware is required
• Check mechanical clearance and length added by the inline adapter

Usage recommendations

For reliable RF performance, ensure clean, undamaged connector interfaces before mating, tighten connections to the recommended torque, and protect exposed outdoor joints with weatherproofing measures. Use this N female to N male barrel adapter when you need a compact, threaded solution to join or adapt N-type terminated cables and antennas in networking and measurement applications.
