Except for one thing. You can do experiments to show that if you 
substitute a less lossly feedline, the losses decrease, or a more lossly 
feedline they increase.

In this case, the mismatch condition still exists, the only thing changed 
was the loss of the feedline. If the mismatch were the cause of the loss, 
one would think it would remain constant when the feedline is substituted.
