Nope, "purely real" requires a special expensive line. I
forget what they call it. Ordinary feedline is not purely
real however close it might be.

I don't care how much it costs, your line
is NEVER going to be 100% purely real! There
is always a gap between mathematical ideals
and reality.
So i totally agree with you.
But for most practical calculations,
Zo can be considered purely real, and your
calculations will be close.
