Look at the end of the cable. If the insulation between the outer shield
and center conductor is a hard and solid material the velocity factor will
probably be 0.66. If this insulation is a soft foam material it will be
between .72 and .80.
Is the cable the size of RG8/213 or LMR400?
If the cable has a thin foil layer on the inside insulator then it will
most likely be LMR400. RG8/213 has no foil lining.

What velocity factor would you use to measure the physical length of a
cable when you don't know the cable type?
