Refractive Index of Coaxial Cable

[Benjamin Irwin]

Anyone know the refractive index of a standard coaxial cable and have a traceable source?

Google knows. Google knows everything...

 

[Tom.G]

Anyone know the refractive index of a standard coaxial cable and have a traceable source?

It's the reciprocal of the propagation constant, which is usually listed in the data sheet for the cable.
Or equivalently: {speed-of-light-in-vacuum} / {propagation-velocity-in-the-cable}.

a traceable source

That would be the spec sheet of the cable you want to use.
