Barrel Adapter alfa network ASP-NM-NM N male to N male coaxial connector

The alfa network ASP-NM-NM barrel adapter is a compact coaxial coupling that connects two N male terminated cables. Designed for situations where continuity of an N-male interface is required, this passive metal adapter simplifies extending antenna leads, joining RF cables, or creating temporary links in networking and test setups. Its straightforward construction provides a durable connection without altering signal polarity or introducing active components.

Advantages

This barrel adapter offers a simple and reliable mechanical join between two N male connectors, enabling quick installation and removal. The all-metal construction ensures good mechanical strength and shielding for RF signal paths, while the small form factor minimizes added bulk in cable runs. Because it is passive, it does not require power or introduce additional electronics that could affect signal behavior.

Suitable for

• Extending antenna cables for Wi‑Fi or cellular systems
• Joining coaxial RF lines in laboratory and test environments
• Temporary connections during installation or troubleshooting of networking equipment
• Connecting N‑male terminated patch cables and jumpers

Key specifications

• Connector type: N male to N male barrel coupling
• Physical construction: metal body for mechanical strength and shielding
• Usage: passive, no power required
• Compatibility: standard N‑series coaxial cables and antennas
• Form factor: compact inline adapter for minimal added length

How to use

To use the adapter, align the N male connectors of the two coaxial cables and gently screw each cable’s connector onto one end of the adapter until hand-tight. Avoid over-tightening with tools to prevent damaging connector threads. Verify that the joined connection is secure and that cable routing does not place stress on the adapter or connectors. The adapter can remain in-line for permanent or temporary installations as required.

Usage recommendations

For best RF performance, use the adapter with cables and antennas that match the N connector standard and ensure connectors are clean and free of debris before coupling. In outdoor or exposed installations, consider adding weatherproofing such as tape or a protective cover around the joint to prevent moisture ingress and corrosion.
