At what frequency did you make that capacitance measurement, and how did you make it? When the frequency is high enough that the cable you are measuring is longer than about 1/20 wavelength (taking Vp into account), the behavior of the cable as a transmission line will cause measurement error. 73, Jim K9YC _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
