Description
The UHF series, commonly referred to as the PL-259, is a rugged and reliable interface traditionally used for HF and VHF applications. This male (plug) variant is specialized for subminiature cables, including the low-loss LMR100, flexible RG174, and high-temperature RG316. While UHF connectors are typically associated with much larger cables like RG8 or RG213, this micro-bore version provides a critical solution for technicians needing to interface small-form-factor wireless devices or test equipment with standard amateur radio, maritime, or public safety hardware.
This connector utilizes a professional crimp termination system for the outer ferrule, ensuring a secure 360-degree mechanical bond with the cable’s shielding. Due to the very thin center conductor of micro-cables, the connector features a precision-machined internal center pin to ensure reliable mating with standard SO-239 jacks. Manufactured with a nickel-plated brass body and premium dielectric insulation, it is built to provide a stable, vibration-proof connection for localized antenna runs and RF test lead fabrication.
Key Technical Advantages
-
Micro-Cable Precision Calibration: Specifically engineered to fit the dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring a high-strength mechanical bond and preventing cable pull-out.
-
Integrated Center Pin: Features a dedicated gold-plated center contact to provide a secure fit within standard UHF female ports, compensating for the thin gauge of micro-coaxial cores.
-
Rugged Mechanical Interface: Combines the flexibility of subminiature cabling with the heavy-duty threaded coupling of the UHF standard, ideal for mobile and field applications.
-
Consistent Signal Integrity: Engineered to maintain stable performance up to 300 MHz (VHF), making it suitable for specialized monitoring and localized signal distribution.
-
Corrosion-Resistant Construction: The nickel-plated brass body and high-grade dielectric ensure long-term protection against oxidation and environmental wear.
