TNC (Threaded Neill-Concelman) Connectors are an enhanced version of BNC connectors, utilizing a threaded interface for improved mechanical strength and environmental sealing. TNC connectors can support frequencies up to 11 GHz and are commonly used in high-frequency applications such as radio communications, microwave systems, and antenna connections.

The threaded design ensures that TNC connectors can withstand harsh environmental conditions, making them suitable for outdoor equipment, aerospace, and military applications where durability and consistent electrical performance are required over time.
