The History of BNC Connections

Chances are you’ve seen a BNC cable before and you have also probably used some sort of instrument with a BNC connection. So where did this common cable come from? This bayonet locking mount device was invented by Paul Neill and Carl Concelman, (BNC, get it?). They worked for Bell Labs and Amphenol, respectively. Paul Neill was also the inventor of the N connector as well. The purpose of the BNC connector was to reduce signal reflection or loss by creating a tight connection between the cable and the instrument.

If you have ever used a BNC cable, you know the locking function of the cable creates a nice, tight connection. Both BNC male and BNC female connections are designed to have a solid connection after quite a bit of wear. A patent was granted for this cable connection in 1951.

Intended for military use, the BNC cable has become synonymous with amateur radio, especially in big rigs. BNC female connections are also found on the back of many composite video devices. Rather than using the more popular RCA connections, many commercial devices opted to use BNC because of the low signal loss. BNC didn’t catch on with consumer devices because of the already existing dominance from RCA.

From video to aerospace, BNC is a connection that can be found pretty much anywhere! Chances are, you own a device with a BNC female connection on the back; so why not get a cable that utilizes this strong connection? Create a BNC cable connection today with Coaxicom!
