TNC (Threaded Neill-Concelman) connectors are threaded RF connectors designed for reliable performance in high-vibration environments. As a threaded version of the BNC connector, TNC offers superior mechanical stability while maintaining a similar form factor. These 50Ω impedance connectors operate effectively up to 11 GHz, making them ideal for telecommunications, aerospace, and military applications where secure connections and signal integrity are critical. Their rugged construction and weather-resistant variants ensure dependable performance in demanding conditions.

Category Insights

TNC connectors typically support frequencies up to 11 GHz, with performance varying based on connector quality and installation. Precision versions can maintain good electrical characteristics across this entire range, while standard versions may show increased VSWR above 6 GHz. The threaded design provides more stable performance at higher frequencies compared to BNC connectors, making TNC suitable for microwave applications where vibration resistance is required.
TNC connectors use a threaded coupling mechanism instead of BNC's bayonet-style lock, providing more secure connections in high-vibration environments. While both support similar frequencies (BNC up to 4 GHz, TNC up to 11 GHz), TNC's threaded interface offers better mechanical stability and weather resistance. BNC remains popular for quick-connect applications, while TNC is preferred for permanent or harsh-environment installations.
Standard TNC connectors are not fully waterproof, but weather-resistant versions with sealed designs and O-rings are available (typically IP67-rated). These environmentally sealed TNC connectors are commonly used in outdoor wireless systems, marine applications, and military field equipment. Proper installation and periodic maintenance are required to maintain weatherproofing integrity over time.
TNC connectors are widely used in cellular base station antennas, aerospace communications, military radios, and microwave systems. Their vibration resistance makes them ideal for mobile platforms like aircraft, vehicles, and ships. They're also found in test equipment and wireless networking gear where reliable connections are more important than quick disconnects.
Proper torque (typically 12-15 in-lbs) is critical to ensure good electrical contact without damaging threads. Use a torque wrench for consistent results, especially with delicate cable assemblies. For outdoor installations, always use weatherproof versions and apply dielectric grease to threads. Avoid over-tightening, which can deform the center conductor. Regular inspection is recommended for connectors in high-vibration applications to detect loosening or wear.
