Yes, and you can see this difference in mfr data sheets that are 
sufficiently detailed (Belden, for example). The differences are 
greatest at the lowest frequencies.

Note also that copper clad aluminum does not suffer nearly as much from 
this, so I suspect it's the effect of the steel on the distribution of 
current. For example, loss in LMR400 (Cu clad Al) is quite close to 
solid Cu of the same diameter (Commscope 3227, #10 solid copper, same 
shield as LMR400) on 160M.
