N Male to UHF Female Adapter SO-239 Pack of 10 - Low Loss RF

Our review of this N male to UHF female adapter pack finds it best suited for hobbyists and RF technicians who need reliable, low-loss gender adapters for antenna and radio connections. The single biggest reason to buy is the combination of brass copper construction and nickel plating that yields a very low signal loss (0.1) and a low VSWR (1.15 at 6000MHz), so users who care about preserving RF performance will appreciate these connectors in everyday use.

Key Features

• Low loss and low SWR: The adapter reports only 0.1 signal loss and a VSWR of 1.15 at 6000MHz, which helps maintain signal integrity in high-frequency links.
• Copper inner conductor: A copper inner sleeve reduces resistive loss, improving overall transmission for critical RF runs.
• Nickel-plated brass body: The brass construction with nickel finish provides corrosion resistance and durable mechanical threads for repeated connections.
• 50 ohm compatibility: Built as a 50 ohm adapter, it lets you join N-female to UHF-male (SO-239) coax lines without disrupting characteristic impedance.
• Wide RF applications: Suitable for antennas, wireless LAN devices, LMR coax, broadcast and external radios, so it covers many common installations.

Who It's For

This pack of ten adapters is aimed at radio amateurs, small broadcast installations, and network technicians who frequently mix N and UHF connector types and need a cost-effective way to adapt between them while preserving RF performance. It is particularly useful for bench work and field deployments where maintaining low SWR is important.

Those who should look elsewhere include users requiring weatherproof, bulkhead-mounted specialty adapters or precision laboratory-grade calibration adapters; this product is a practical, general-purpose connector rather than a sealed outdoor feedthrough or a metrology-grade standard.

Pros & Cons

Pros

• Low measured signal loss and modest VSWR make these adapters suitable for high-frequency RF links.
• Solid nickel-plated brass and copper inner construction offers good mechanical durability and reduced corrosion.
• Pack quantity provides value for workshops, repeaters, and multi-cable installations.

Cons

• Not a weather-sealed or waterproof adapter, so outdoor use requires additional protection.

Specifications

Our Verdict

These N male to UHF female adapters offer solid value for anyone adapting between N and SO-239/UHF connections while keeping losses to a minimum. They are well made, perform with low VSWR, and come in a practical pack size, making them a smart purchase for radio enthusiasts and technicians who need dependable, general-purpose RF adapters.

Frequently Asked Questions

Can these adapters affect my antenna SWR?
When used correctly they have low loss and a VSWR of 1.15 at 6000MHz, so they should not noticeably degrade overall antenna SWR in typical installations.

Are these suitable for outdoor use?
The adapters are nickel-plated brass but not weather-sealed, so outdoor installations should include a protective boot or sealing to prevent corrosion.

Will they fit common LMR and coax cables?
Yes, as 50 ohm N-to-UHF adapters they are intended to connect N-female to UHF-male (SO-239) style cables and devices commonly used with LMR and similar coax.
