Description
The TNC (Threaded Neill-Concelman) series is a high-reliability version of the BNC interface, designed to maintain signal continuity in environments prone to shock and vibration. This male (plug) variant is specifically optimized for the 7.6mm (0.300″) cable class, providing an ideal termination for LMR300 low-loss coaxial cables. It serves as an essential bridge for applications requiring lower attenuation than LMR240 while maintaining the mechanical stability of a threaded interface in outdoor or mobile deployments.
This connector utilizes a professional dual-crimp termination system. The outer ferrule creates a 360-degree mechanical bond with the cable’s braid and foil shielding, while the precision-machined center pin is crimped to the internal conductor. Manufactured with a heavy-duty nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent performance up to 11 GHz. The threaded interface provides superior EMI shielding and environmental resistance, making it ideal for Wi-Fi backhaul, GPS distribution, and tactical communication systems.
Key Technical Advantages
-
LMR300 Precision Calibration: Specifically engineered to fit 0.300-inch OD cables, ensuring an optimized electrical transition and high-strength pull-off resistance for high-efficiency cable runs.
-
Vibration-Proof Threaded Interface: The 7/16-28 threaded mechanism ensures a constant mechanical and electrical connection, preventing signal intermittent issues in high-G or outdoor applications.
-
Low-Loss Signal Integrity: Designed to complement the high-performance characteristics of LMR300, maintaining low VSWR and stable 50-Ohm impedance across the frequency spectrum.
-
Rugged 360° Crimp Termination: The heavy-walled ferrule provides a permanent, airtight grip on the cable jacket, protecting the internal dielectric from moisture ingress and mechanical stress.
-
Superior Environmental Durability: The nickel-plated brass construction and PTFE dielectric offer excellent resistance to thermal cycling, oxidation, and UV exposure in tower-mounted or marine systems.
