I would suggest putting a 50 ohm dummy load on one end and measuring SWR with 
your MFJ from the other end.  Won’t be a perfect match but around 1.5’to 1.7.  
The key indicator of cable integrity is when you vary the frequency of your MFJ 
the SWR should stay relatively constant versus jumping all over.  If SWR varies 
widely, I’d bet the cable is bad.

Not perfect, but it should get the job done given the tools you have on-hand.
