For a VSWR so bad, one would expect a cable fault. I assume that you've checked for short circuit between signal and screen conductors, and open circuit faults too?
Are you adapting from one cable type to another? Or in other words, how are you adapting from SMA to BNC?

Yes - that means there is a very serious fault - short circuit of the cable or open cable (fully reflected signal).
