If you are referring to the connectors on the R-390A, the correct
nomenclature is MB series.  They are often referred to a "mini BNC" but that
is not correct.  They were not widely used and a little difficult to find.
The last I knew Skycraft Surplus in Winter Park, FL had some stock or
William Perry Co, in Louisville, KY may have them.
