How to Attach a Crimp-On BNC Connector

A BNC Connector (short for “Bayonet Neill-Concelman”) has been used since the 1940s in military and electronic applications. You’ll find them in TVs, radios, networking devices, cameras, monitors, and oscilloscopes—essentially anywhere coaxial cables are terminated. Here’s how to attach a crimp-on BNC Connector.
