Why should you use BS EN 4652-212 - Square flange receptacle coaxial connectors?       
The TNC connector (acronym of "Threaded Neill–Concelman") is a threaded version of the BNC connector. The interface specifications for the TNC and many other connectors are referenced in MIL-STD-348. The connector has a 50 Ω impedance and operates best in the 0–11 GHz frequency spectrum. It has better performance than the BNC connector at microwave frequencies. BS EN 4652-212, manufacturers can demonstrate the reliability of their products and build trust in their use throughout the aerospace supply chain.            
Quality assurance measurements in BS EN 4652-212 ensures that the approaches, techniques, methods, and processes designed for the aircraft electrical systems are implemented correctly. BS EN 4652-212 is important because it enhances quality and user satisfaction. It can boost the customer’s faith and confidence with the aircraft and enhance their experience working with the aircraft in the long run.
