title_body: What are the exact specifications of a RushFPV SMA connector? I am designing a mount for a RushFPV SMA connector and have not been able to find the technical details.
  
  I need:
  
  The diameter of the connector 
  
  The distance between the mounting screw holes
  
  The dimensions of the mounting plate in which the holes are cut.
  
  If anyone has this information, I would be very grateful.
  
  Thanks.
upvoted_answer: The Rush cable is slightly non-standard as it lacks the threads on the holes that the TBS connectors have. It works fine though. The SMA is a standard SMA thread, so the normal hole size for SMA connectors works well. In my designs I usually use a 6.5mm hole for SMA, though some of that depends on the tolerances you're dealing with on your machining. The hole spacing for the small mounting holes is 11.5 mm from center to center. I usually use a 1.5mm hole for the bolt for the Rush SMA mounts, as you can thread an M2 bolt right into the carbon without needing an additional nut, but if you're wanting to use a nut, you'll want to increase that to a 2mm hole.
