[RFI] coax shield outside impedance?

I have a question that I've not seen discussed before. Maybe it has 
been, but I don't remember seeing it.

*When attempting to minimze CMI on the outside of 50 ohm coax, the 
shield is not normally 50 ohms. What shield Z do you use for calculating 
the needed choke Z and thus the attenuation to expect?
