You're in a maze of incompatible SMA connectors, all alike. Just updated my SMA tolerance super-reference, with more legacy standards (IEC 60169-15:1979) added. Apparently even big firms like Rosenberger are still making legacy 60169 connectors that violate the modern 61169 protrusion rule. https://gist.github.com/biergaizi/2420faf4fa2dbb8ca4666c3a75918455 #electronics
