TNC Cable Assemblies are strong RF Cables with TNC (Threaded Neill-Concelman) Connectors at one or both ends. These assemblies are frequently utilized in wireless communication systems where durability, vibration resistance, and consistent RF performance are required.
TNC Assemblies are favored over BNC in outdoor and high-frequency situations because of their threaded connection, which provides secure mechanical locking and enhanced electrical contact.
What is a TNC Cable Assembly ?
A TNC Cable Assembly is an RF Coaxial Cable with TNC Connectors crimped or soldered to the ends. These connectors include a threaded coupling mechanism, commonly 7/16-28 UNEF, which provides better vibration resistance and waterproof performance than bayonet-type connectors.
These Assemblies can support frequencies up to 11 GHz, making them ideal for cellular, Wi-Fi, radar, IoT, and military applications.
Key Features of TNC Cable Assembly :
- Threaded coupling provides a secure, vibration-resistant connection.
- Ideal for outdoor and rough deployment.
- Low insertion loss ensures effective signal transmission.
- Supports high-frequency operating up to 11 GHz.
- Superior shielding (single, double, or braided).
- Available in straight and right-angle designs.
- Compatible with common coaxial cables (RG and LMR series).
- RoHS-compliant materials.
- Options for waterproofing and strain relief boots.
