N to N Coax Cable Adapter Double Female Connector - Low Loss RF

In this review the XRDS -RF N to N coax cable adapter is presented for technicians and hobbyists who need a simple, low-loss way to join two N-male coaxial cables. The bottom line: this small double-female barrel connector delivers dependable RF performance with minimal attenuation and robust construction, making it a straightforward choice when extending antenna leads or connecting RF test gear. The review focuses on signal integrity, build quality and common use cases where a 50 ohm N-to-N inline joint is required.

Key Features

• Low loss and low SWR: The adapter attenuates signal only about 0.1 dB and maintains VSWR under 1.15 to 6000 MHz for reliable RF transmission.
• 50 ohm compatibility: Designed as a 50 ohm N-to-N female barrel connector, it pairs directly with N-male coaxial cables to extend runs without impedance mismatch.
• Solid materials: Copper and brass construction with gold and nickel plating provides corrosion resistance and solid electrical contact for stable connections.
• Dielectric reliability: Teflon insulation preserves signal integrity and contributes to the low measurable SWR increase.
• Indoor and outdoor use: Heavy duty finish and plating make the connector suitable for both indoor installations and outdoor RF hardware when mounted or connected properly.

Who It's For

The XRDS -RF N to N adapter is aimed at RF engineers, amateur radio operators, Wi-Fi and wireless LAN installers, and anyone who needs to extend or join coaxial runs that terminate in N-male connectors. Its low insertion loss and controlled VSWR make it appropriate for antennas, repeaters, broadcast gear, and external radios where preserving signal is important.

People who need weatherproofed bulkhead connectors or integrated cable assemblies should look elsewhere; this part is a simple inline barrel connector and does not include gasket seals or meters. It is not a broadcast-ready weather sealed junction by itself without additional protective measures.

Pros & Cons

Pros

• Very low attenuation and stable VSWR, so signal quality is preserved across typical RF bands.
• Durable brass and copper construction with plating gives reliable contacts and decent corrosion resistance.
• Simple, universal 50 ohm N-to-N configuration makes it easy to extend many common RF cables and devices.

Cons

• Not inherently weather sealed, so external installations need additional protection to prevent moisture ingress.

Specifications

Our Verdict

This N to N coax adapter is a no-nonsense, well-built inline connector that preserves RF performance with minimal loss and low VSWR, making it good value for technicians and hobbyists who need to extend N-male coax runs. Buy it when you need a compact, electrically reliable joiner; add weatherproofing if the installation will be exposed to the elements.

Frequently Asked Questions

Can this adapter be used outdoors?
Yes, the metal plating and construction are robust, but it is not a sealed weatherproof connector by itself and should be protected with tape, boots, or an enclosure for long-term outdoor use.

Will this change my antenna tuning?
Practically no; insertion loss is about 0.1 dB and VSWR increase is negligible within the stated frequency range, so tuning should not be affected.

Which cables does it connect to?
It connects two cables or devices with N-male terminations and is intended for 50 ohm coaxial systems.
