Product description
This listing includes two 50-ohm N-male to UHF-female (SO-239) adapters, intended to join N and UHF/PL-259 style coaxial connectors. The center conductor of each coupler is copper to keep insertion loss to a minimum, while the body is machined from brass and finished with nickel plating for durability and corrosion resistance.
Electrically the adapters are specified for low loss — about 0.1 dB — and exhibit a VSWR of approximately 1.15 at 6000 MHz, making them suitable for many RF tasks where maintaining signal integrity is important. They are configured as N-male to UHF-female so you can mate N-female terminations to UHF/PL-259 male plugs without custom cables.
Common uses include antenna connections, wireless LAN devices, coax runs using LMR cable, broadcast links, Wi‑Fi radios, external antenna hookups and repeater equipment. Manufactured by XRDS-RF, these adapters come with a one-year warranty and are marketed as professional-grade RF connectors designed for routine field and bench usage.
Pros
- Low insertion loss and low VSWR
- Durable nickel-plated brass construction
- Includes two adapters for convenience
Cons
- Occasional center pin misalignment
- Fit can be tight on some mating connectors
- Not intended for television coax applications
VerdictThese N-male to UHF-female adapters offer clean mechanical fit and low electrical loss for RF hookups. Constructed with copper inner conductors and nickel-plated brass shells, they maintain a low VSWR and are suitable for many antenna and test applications. They’re useful when converting between N and SO-239/PL-259 systems and come as a pair with a one-year manufacturer warranty. Occasional minor

High-quality coupling for test gear
I connected an RF amplifier to a coaxial directional coupler to inspect harmonics with a spectrum analyzer. The adapters performed reliably with no unexpected losses.

Solid connectors for repeater work
Managing multiple repeaters, I needed dependable adapters. The nickel-plated brass units have held up on duplexers and during spectrum analyzer testing. Easy to fit and well made.

Handy for adapting dummy loads
Two dummy loads had Type N males while my gear uses PL-259. These adapters let me avoid making new cables. Finish and fit are substantial.

Works perfectly with my Comet CA-712EF
I used this Type-N to UHF adapter to join LMR-400 to a Comet CA-712EF that had a female N. No measurable SWR change and solid electrical contact. Threads are well cut and it mates cleanly to both ends. Very pleased.

Mostly perfect fit
One unit arrived with a slightly bent center pin but it was easy to straighten. Otherwise the adapters fit well and work as expected.
