I have a device with an RF connector similar to SMA but failed to find the type number of this connector or the specification anf if any body know any distributor for such connector.
Any Help is appriciated

Hi there,
I found this web page about Russian RF connectors (with reference SR-50-164PV and SR-50-164FV):
http://qro-parts.com/images/Connector/cp50final.htm
Unfortunately, these look like N type kind of connectors, but may be these references could be a starting point to find a distributor of Russian connectors.
Good luck...
