• Hi,
  
  I’m working on this project with Russian/Soviet RF connector as I list in attach files.
  
  To anyone who knew, please help me identify this connector.
  
  Thanks in advance!

• How close is it to a TNC?

• I am looking at a TNC. Your connector is not a TNC.
  
  TNC male looks almost identical to a BNC except it screws on, it does not lock on with a spring lock. It has a sharp machined pin with a conical tip, like a BNC.

• Check  dimension. Possible this is very old obsolete connector from GOST 20265-74

• It is quite large from the pix & spec sheet, & looks a lot like a Chinese L27 connector.
  The latter are available from the PRC, but are not cheap.
