Description
The UHF series is a rugged RF interface designed to handle significant power levels in HF and VHF applications. This male (plug) variant is specifically optimized for the 10mm (0.400″) cable class, accommodating high-performance cables such as the low-loss LMR400, industrial RG213, and the high-temperature/high-power RG393. Its large-bore entry ensures a precision fit for the expanded dielectric and heavy-gauge conductors found in these high-bandwidth feeder cables.
This connector utilizes a professional crimp termination system for the outer ferrule, providing a 360-degree mechanical bond that offers superior pull-off resistance compared to traditional twist-on types. The center contact is typically terminated via soldering to ensure maximum power handling and a low-resistance electrical path. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it maintains exceptional signal integrity and mechanical stability even under high-torque conditions or high-vibration environments.
Key Technical Advantages
-
Large-Diameter Precision Fit: Specifically calibrated for 0.400-inch OD cables, ensuring a seamless mechanical transition and preventing signal bottlenecks in high-power runs.
-
High-Strength Crimp Termination: The heavy-walled outer ferrule provides a permanent, vibration-proof grip on the cable jacket and shielding, essential for tower-mounted antennas.
