"Reg, G4FGQ observed on these pages long ago that an ordinary ohmmeter would read Zo if connected to the end of an infinite line. He is right of course." But the Zo of a line varies with frequency. How will the "ordinary ohmmeter" do the job at, say, 100 kHz? 73 de jack YOu should get a lot of people calling BS on the Zo changing with frequency. It does not change at any reasonable frequency for the line. That is at least anything below 1 ghz for coax. |
