The following message was posted to my BBS a few days ago. I thought the net would be interested... >Fm: PHIL RANE (Compuserve 74075,1244) >To: all Some time ago we had a lengthy discussion about the origins of the coax connector names such as BNC, TNC, etc. I have just come across an article in QST, a Ham magazine that I think is the real McCoy. I would like to share it with you. Quoting: During WWII, the requirements for connectors better than the UHF PL-259 and SO-239 ones, to be used for radar use, prompted two designs. The first was developed at Bell Labs by Paul Neill and identified as the type N connector. At the same time, another connector was devised by Carl Concelman. Named the type C connector, it was the first designed as a true 50-ohm connector. Later, Neill and Concelman collaborated on the design of a minature bayonet locking connector. This was dubbed the Bayonet Neill-Concelman, or BNC connector. Some time after that, an improved, threaded version for airborne use was developed and called the Threaded Neill-Concelman or TNC connector. For precise microwave use, a series of subminature connectors was produced- A, B, and C. Of these three, the A, or subminature (SMA) is the most popular.

The legend, as told by a foreign-born professor of electrical engineering here at Penn, is that the BNC conncector is so named because it is a Berry Nice Connector. Scott Green

They are rather hard to find (maybe I haven't looked hard enough), but they are great for making portable and mobile 2-meter antennas! I had a friend in Salt Lake City who used one on his car (5/8 wave 2m antenna), and it lasted quite a long time! For those of you who are not familiar with the type C connector, it's like a BNC, except larger. Bayonet mount, the whole shot. Much nicer than type N.

I didn't see the original article to this but from what I remember it went: BNC : Bayonet Navy Connector. TNC : Threaded Navy Connector. N : Navy connector (Presumably) Perhaps the navy needed a better connector than the then standard UHF (sic) connector, considering the harsh corrosion environment.
