	Regarding this whole issue, shortly after I posted the referenced
article, I decided to again browse through my organization's library, and
I have now found a reference: the 1979-1980 Hewlett-Packard "Coaxial and
Waveguide Catalog", which states on page 91:

	"The BNC (Bayonet Navy Connector) connector was originally designed
for the military during World War II." [additional text deleted].

	"The TNC (Threaded Navy Connector) connector is merely a threaded
BNC." [additional text deleted].

	I place great value on the above information coming from a source
such as H-P.

	This information confirms what strong@tc.fluke.COM (Norm Strong)
has posted.  I apologize if I have doubted him, but with so many conflicting
definitions that were posted (from "Baby N" to "Berkley Nucleonics" to
claiming that the letters stood for people's initials), I simply did not
believe ANYONE until I could find a reference.

	I am rather surprised that this connector originated during World War
II.  I could find no reference to it in the MIT Rad Lab series.  While
I did not check every Rad Lab volume, I did check those which seemed
appropriate.  This seems to be an unusual omission.  Just about EVERYTHING
pertaining to radar and UHF that was developed during World War II is
discussed or illustrated somewhere in the Rad Lab volumes.

	Incidentaly, the H-P catalog also says that the "N" connector
stands for "Navy".  Does that mean that the "C" connector (a large
BNC-type) stands for Coast Guard? :-)
