Velocity Factor (VP) for RG8X?
"Cecil Moore" wrote in message . com... Reg Edwards wrote: And the same applies to impedance Zo and attenuation. How much could the Z0 vary for "50 ohm" coax? -- ================================= For coax, Zo = 60 * VF * Ln( D / d ) So Zo varies as VF varies. You'll just have to measure VF or Zo. Similar for attenuation. ---- Reg. |
