Tektronix 1502 TDR or equivalent..... no connectors needed. Measures the
length pretty well too and sees any impedance flaws. Especially bullet

coaxial cable for sale. Often unused, left over from a project, on a
reel, pickup only, as-is where-is, cash. If one were to pursue such a
purchase, what would one look for and/or do to validate that the cable
is good?
these days, a $50 VNA to do a synthetic TDR would be good. Fits in a
shirt pocket and you could use a SMA to cliplead adapter. I wouldn't
even necessarily try to calibrate it.
