TNC Female to TNC Female Adapter

Description

The TNC Female to TNC Female Adapter is a robust “in-series” coupler used to bridge two male TNC interfaces. While standard BNC connectors use a bayonet mount, the Threaded Neill-Concelman (TNC) interface utilizes a 7/16-28 threaded coupling to ensure the connection remains stable under extreme mechanical stress and high-vibration environments. This makes it a primary choice for avionics, satellite telemetry, and industrial RF manifolds.

These adapters are typically machined from Nickel-plated or White Bronze-plated Brass to resist corrosion and wear. The internal center contacts are often Gold-plated Beryllium Copper to maintain low contact resistance and high signal integrity across thousands of mating cycles. With a high-grade PTFE (Teflon) dielectric, they achieve low insertion loss and a low VSWR, making them suitable for high-bandwidth data transmission and sensitive measurement setups.

Key Technical Advantages

• Rugged Threaded Locking: The 7/16-28 threads provide a secure “locked” connection that outperforms bayonet-style connectors in high-vibration or tactical mobile applications.

• Wideband 11 GHz Performance: Optimized for stable electrical performance from DC up to 11 GHz, covering all sub-6 GHz 5G bands, Wi-Fi 6, and many microwave applications.

• Superior Signal Integrity: Engineered for ultra-low insertion loss (≤0.15 dB) and a low VSWR, ensuring maximum power transfer and minimal signal reflection.

• Environmental Resilience: Often designed to be moisture-resistant, many TNC adapters meet IP67 or IP68 standards when properly mated, making them ideal for outdoor towers.

• High Power Capacity: Due to its medium-sized physical footprint, it can handle higher power levels than sub-miniature SMA connectors while remaining more compact than N-type interfaces.
