The PL-259 (UHF male) is the standard coaxial connector used in ham radio, CB radio, marine VHF, and video headend applications. This solder-type version is designed for building or repairing coaxial cable assemblies with larger-diameter cables — RG8, RG8x, RG59, RG213, LMR-400, LMR240, and 4D-FB. A cable diameter reducer is included in the pack to accommodate the range of supported cable sizes without needing separate adapters.
The PTFE (Teflon) dielectric is the key differentiator from standard PL-259 connectors. PTFE withstands soldering temperatures up to 260°C without melting or deforming, which is essential when using a high-wattage iron for a secure center pin solder joint. Cheaper connectors with polyethylene dielectrics can melt during soldering, causing shorts or poor RF performance. The gold-plated center pin and body resist corrosion and oxidation, maintaining low contact resistance over time. All connectors are 50 ohm, matching the impedance of the supported cable types.
Soldering skill is required — this is not a crimp or clamp connector. The installer needs to strip the cable correctly, tin the braid and center conductor, and solder both the center pin and the braid through the body solder holes. This connector is not suitable for RG58 or RG174 thin cables, which require a different PL-259 body size. For crimp-type PL-259 connectors or connectors sized for thinner cables, see other Onelinkmore listings.
Frequently Asked Questions
Yes, PL-259 and UHF male refer to the same connector. "PL-259" is the military designation for the plug (male), while "SO-239" is the military designation for the socket (female). "UHF connector" is the common commercial name for this connector family. Despite the "UHF" name, these connectors are historically used at HF and VHF frequencies — they are not precision connectors above ~300 MHz due to their non-constant impedance geometry.
No. This PL-259 body is sized for larger cables — RG8, RG8x, RG59, RG213, and LMR-400, which have outer diameters of approximately 6–10mm. RG58 has an outer diameter of approximately 5mm and requires a smaller PL-259 reducer or a different connector body. Using this connector on RG58 will result in a loose fit and unreliable termination.
When soldering the center pin, the iron tip comes very close to the dielectric material inside the connector. Polyethylene (PE) dielectric melts at around 120°C and can deform or flow into the solder joint, causing a short circuit or a mechanically weak connection. PTFE (Teflon) has a melting point above 260°C, so it remains stable even with a high-wattage iron. This makes PTFE connectors significantly more reliable for field and workshop assembly.
The reducer is a small ring that threads into the rear of the PL-259 body and reduces the cable entry hole diameter. Different cables have different outer diameters — for example, RG8x is thinner than RG8 or LMR-400. The included reducer allows this one connector to fit the range of compatible cable sizes. Select the correct reducer size for your cable before assembly.
Yes. PL-259 connectors are standard on marine VHF radios and antennas. For marine installations, the gold plating on this connector provides corrosion resistance in saltwater environments. After assembly, applying self-amalgamating tape over the connector body and cable junction is strongly recommended for any exterior or below-deck installation exposed to moisture.
The PL-259/UHF connector is not a precision RF connector and does not maintain constant 50 ohm impedance at higher frequencies. It is commonly used up to around 300 MHz for ham radio HF/VHF and CB applications. For UHF frequencies (above 300 MHz) or microwave applications, N-type, SMA, or BNC connectors are the appropriate choice. For 2m (144 MHz) and 70cm (432 MHz) ham radio use, PL-259 is acceptable but N-type is preferred for lower loss.
