I've always taken it for grunted
I have often grunted when taking transmission line measurments, but I try to keep it to a low volume. Your ohmmeter will budge if you terminate the line with a short, or some resistance. The Characteristic Impedance (300/75/50 ohms) is an AC or RF measurement, and can not be done with a DC VOM. The devices that the average Ham has on hand include, antenna analyzer, grid dip meter, and rf signal generator. Transmission line measurements with these devices can been found in the ARRL books or with the instruction books with the instruments. 73 Gary N4AST |
