I have a coax connector that I would like to identify. Se attached
picture.
To the left is a female TNC for reference. The unknown male is attached
to the cable. Unknown female to the upper left as part of a "T" adapter.
It looks kind of a smaller version of TNC. It is slighly larger than
SMA. Female diameter is 5/16", whereas TNC is 7/16" and SMA is 4/16" -
according to my simple measurement.
Anyone recognizing this connector?

Hi Bjorn
Quick answer is no, but "miniature TNC" would seem to be a possible
contender.
Unfortunately, although I've seen enough references to miniature TNCs to
know they exist, I've not yet found a photo or drawing.
I'm pretty sure I have some equipment with them fitted but, if I have, it
will be in storage so not something to be confirmed in a hurry.
What you've got, as you say, is certainly not SMB or SMC but is about the
same size as SM.
And yes, that is SM and not SMA.
The SM connector, not very common but I've got some Greenpar SM adapters, is
similar to SMA, in terms of pin and dielectric arrangement, but bigger,
whilst what you have is a very close match to the TNC configuration, but
smaller.....
so, in size at least, they sort of meet in the middle:-)
A while ago I bought a Greenpar adapter kit that was a special for the UK
military and probably the biggest kit Greenpar made.
Alongside most, if not all, the common connectors we're all used to was
quite a range I'd never heard of before, including SM, HN, SC, Pattern 8, Pattern
12, etc etc.
They generally seem to be a "close but not quite" match to more common
connectors but so far I've not seen any of them in commercial catalogues.
I suspect your connectors might be similarly unusual but still think Mini
TNC is the most likely option..... although happy to accept that somebody will
probably prove me wrong within a few minutse of this being posted:-)
