When putting up an antenna, do you use different Zo coax for 2 Vs. 80 meters
to account for frequency change? The Zo is constant for all practical purposes below Giga Hz freqs. "JDer8745" wrote in message ... Someone sed, "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 |
