Re: 11048C feed through termination data?

This is a good example of how facts can be distorted on the internet. What does the existence of this document prove? It is not SOLELY Navy. In WWII, the Army-Navy R-f Cable Coordinating Committee (its given name) was in charge of specifying and assuring compatibility of coax connectors and cables, as well as their performance. The document from the Navy radio site is not a Navy document per se, but a JOINT Army-Navy document and the result of this committee. It morphed into MIL HDBK 216 and was in effect until 1972, when RG- cables (Radio, Guide)? were superseded by MIL-17 definitions.
AT NO PLACE in ANY document, so far, has there been reference to the Neill connector as a Navy Connector.
Instead, I posit that EVERYONE at the time, knew Neill had invented it and so it was shortened to N. Same with the C connector from Concelman. What is the ALTERNATIVE definition for "C"? Cable, Cherries, Cheese, Coax. No, I think since the N predates the 1945 document by many years, that document is not the definition of it, merely a tabulation of properties and specifications for an existing product. The Bell System Journal would yield the dates and I may research this to quash the foolish "Navy" definition.
Show me in print an official document of the US government that defines the "N" connector as being "Navy" connector or give up. Your definition is anecdotal at best, and based on "what Joe told Sam" whereas we have Neill as the named inventor. I assure you, you cannot find ANY prewar document that specifies the US Navy as specifying a 1 GHz connector like the original N as "Navy", long before the "Navy" had any use for it.
BTW Nick has a great site, I see him often at hamfests.

A group member sent me a document off-list that discussed naming. I can't share it but the refences were mostly personal communications. Interestingly one reference lead me to NAVSHIPS 900102. There is a copy here:

It's a contempary (1945) description of coaxial cables and connectors. No mention of Neill or Concelman but it does refer to N and BNC series as well as BN, LN and HN. Interestingly it compares the N series to "the orginal N connector". I now wonder if this original N was the "Naval" connector.
Even more interestingly it clearly describes the BN as "Baby N" (It is a small connector with threaded coupling now completely obsolete) and the BNC as an improved BN connector with improved construction giving constant impedance hence Baby N Constant-impedance.
So while the accreditation of the N and BNC designations to Neill and Concelman may have occoured later (and Bayonet N Compact) Clearly this was not the case at the time they were introduced.
Things have obviously changed over the years.
looks like a great resource and a new one to me.
