Product Description
Product Description
The Type N Male to UHF Female (SO-239) Coaxial Adapter provides a convenient connection between radio equipment equipped with a 50-ohm Type N male interface and standard UHF-male (PL-259) coaxial cables. It combines the high-frequency performance and weather-resistant threaded interface of a Type N male connector with the widely used UHF/SO-239 female connection.
Designed for RF, amateur radio, GMRS, antenna, and communications applications, this adapter offers a practical solution for connecting equipment with different coaxial connector standards. The Type N side provides a true 50-ohm interface for low-reflection RF performance, while the UHF female side is well suited for lower-frequency HF and VHF applications.
Specifications
Connector Configuration: Type N Male → UHF Female (SO-239)
Connector Thread: 5/8"-24 UNEF
Impedance: 50 Ohms
Typical Frequency Range: DC–300 MHz (UHF)
Typical Frequency Range: DC–11 GHz (Type N)
Key Features
- Type N Male to UHF Female Adapter — Connects equipment with a Type N male jack to standard PL-259/UHF-male coaxial cables.
- 50-Ohm Type N Interface — Provides a true constant-impedance 50-ohm connection for reduced signal reflections and reliable RF performance.
- UHF Female / SO-239 Interface — Uses the standard 5/8"-24 UNEF threaded coupling for compatibility with PL-259 male connectors.
- Broad Type N Frequency Capability — Type N interface supports applications from DC up to 11 GHz, depending on system and connector design.
- Best Suited for Lower-Frequency UHF Performance — The SO-239 side is commonly used from DC through approximately 300 MHz, with performance becoming less ideal as frequency increases.
- Rugged RF Construction — Typically manufactured with a nickel-plated brass body, plated contacts, and a high-quality dielectric insulator.
- Quality Insulation — PTFE or comparable high-grade dielectric materials provide reliable electrical isolation and durability.
- Threaded, Secure Connection — Both interfaces use threaded coupling mechanisms for a positive mechanical connection.
- Versatile Applications — Ideal for amateur/ham radio, GMRS base stations, mobile radio setups, antennas, RF equipment, and communications systems.
- Practical Connector Conversion — Provides an easy way to integrate equipment using different RF connector standards without replacing existing coaxial cables.
Typical Applications
- Amateur / ham radio equipment
- GMRS base and mobile radio systems
- RF and antenna installations
- HF and lower-VHF applications
- Broadcast and communications equipment
- Antenna feedlines and coaxial cable assemblies
- Connecting Type N equipment to PL-259/UHF coaxial cables

First Class
I take RF adapters seriously as they are mode enablers. The N-to-UHF I purchased from American Radio Supply is a high quality unit that I have faith in under difficult conditions. Highly recommended.
-
Well Made
I haven't run any performance tests on this connector but it appears to be well made with no cosmetic blemishes. I use it to change the N connector on my Comet antenna analyzer to my standard UHF connectors.

★★★★★
Got caught in the field with the wrong antenna, one with type N. I handled it by using my truck antenna but I'll never get caught that way again. This simple adapter is all I needed.
