[QUOTE="Sidewinder, post: 392729, member: 9512"] TBH PD, that's not an accurate enough way of measuring it. To get a length for such a cable you, really, need a TDR & the full cable spec from the manufacturer to enter into the TDR, that will then give you an accurate length. The cable may have a lower dc resistance than the "standard" spec and still be "in spec". dc resistance is pretty much irrelevant for a balanced transmission line. Come on PD, you understand this stuff I'm sure. [/QUOTE]
