UHF Male & N-Type Male RF Connector – Gold-Plated Brass Crimp for RG58 / RG59 / RG6U Coaxial Cable

Gold-plated brass crimp RF connectors for UHF (PL-259) and N-type coaxial cable terminations. Used for antenna connections, RF equipment interfaces, and coaxial cable assemblies in amateur radio, CB radio, cellular, and broadcast applications. The crimp termination method provides a more reliable, lower-resistance connection than solder-type connectors — eliminating the risk of cold solder joints and providing consistent impedance matching across the connector body.

UHF (PL-259) vs N-Type — Which Connector?

• UHF / PL-259 (this product): The most common RF connector in amateur radio and CB radio. Despite the name “UHF,” the PL-259 is not well-suited for true UHF frequencies above 300MHz — its non-constant impedance design causes significant signal loss above 300MHz. Use PL-259 for HF (1–30MHz) and VHF (30–300MHz) applications: amateur radio HF transceivers, CB radio, marine VHF, and FM broadcast antennas.
• N-type (this product): Precision 50Ω or 75Ω connector rated to 11GHz. The correct choice for UHF and microwave applications: cellular antennas, GPS, WiFi, and any application above 300MHz where signal loss matters. N-type is weatherproof when mated, making it suitable for outdoor antenna installations.
• Selection rule: Use PL-259 for HF/VHF amateur radio and CB. Use N-type for cellular, GPS, WiFi, and any frequency above 300MHz.

RG58 vs RG59 vs RG6U — Cable Selection

• RG58 (50Ω): Thin, flexible. For amateur radio, CB, and 50Ω RF equipment. Maximum run length approximately 30m at 100MHz before loss becomes significant. Use with 50Ω UHF (PL-259) or N-type connectors.
• RG59 (75Ω): Thin, flexible. For CCTV, composite video, and 75Ω RF applications. Lower loss than RG58 at video frequencies. Use with 75Ω BNC or F-type connectors for video; 75Ω N-type for RF.
• RG6U (75Ω): Thicker than RG59, lower loss. The standard for cable TV, satellite, and long-run antenna installations. Use with F-type connectors for TV/satellite; N-type for RF applications requiring longer runs.

Frequently Asked Questions

Do I need a special crimp tool for RF connectors?

Yes. Coaxial RF connectors require a dedicated coaxial crimp tool with the correct die set for the connector type and cable size. A standard wire crimp tool will not produce a correct RF crimp — the die geometry is wrong, resulting in poor impedance matching and high VSWR. For PL-259 crimp connectors on RG58, use a crimp tool with RG58 dies. For N-type on RG58, use N-type RG58 dies. The crimp tool compresses the outer ferrule onto the cable braid in a single, consistent motion — producing a lower-resistance, more reliable connection than solder termination.

What is the difference between crimp and solder PL-259 connectors?

Solder-type PL-259 connectors require soldering the center conductor to the center pin and soldering the braid to the connector body through small holes in the shell. Crimp-type (this product) use a crimp ferrule to mechanically compress the braid onto the connector body — no soldering required on the outer conductor. Crimp connectors provide more consistent results, lower contact resistance, and better weatherproofing than solder types. For field repairs without soldering equipment, crimp connectors are the professional choice.

Can I use a 50Ω connector on a 75Ω cable?

Physically yes, but electrically this creates an impedance mismatch that causes signal reflection (VSWR >1). For low-frequency applications (HF radio below 30MHz), the mismatch effect is minimal and often acceptable. For VHF and above, always match connector impedance to cable impedance: 50Ω connectors on 50Ω cable (RG58), 75Ω connectors on 75Ω cable (RG59, RG6U).

How do I weatherproof an outdoor N-type or PL-259 connection?

Apply self-amalgamating (self-fusing) tape over the mated connector pair, starting 50mm below the connector and extending 50mm above it. Stretch the tape to 50% of its original width as you wrap — this activates the self-fusing property. Apply 3–4 layers minimum. For permanent outdoor installations, apply a UV-resistant outer wrap of PVC electrical tape over the self-amalgamating tape to protect against UV degradation.

Typical Applications
