Description
The UHF series (PL-259) is the global standard for high-wattage HF and VHF signal distribution. This male (plug) variant is specialized for RG217, a high-performance, double-shielded cable with a significant outer diameter (approx. 13.8mm / 0.545″). Due to the increased thickness of RG217 compared to standard RG8/RG213, this connector features an expanded body and a heavy-duty ferrule designed to accommodate the cable’s large dielectric and thick double-braided shielding.
This connector utilizes a professional crimp termination system for the outer conductor, providing a permanent, 360-degree mechanical bond that offers superior pull-off resistance for heavy cable runs. The center pin is typically terminated via soldering to ensure a low-resistance, high-conductivity path capable of managing extreme RF voltages. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it provides exceptional thermal stability and durability in high-duty-cycle environments such as radio transmitters and linear amplifiers.
Key Technical Advantages
-
Oversized RG217 Precision Fit: Specifically calibrated for the 14mm-class dimensions of RG217 cable, ensuring a seamless mechanical transition and preventing signal bottlenecks.
-
High-Strength Crimp Termination: The heavy-walled outer ferrule provides a vibration-proof grip on the double-shielded jacket, essential for maintaining signal integrity in high-stress industrial or shipboard environments.
