    I never saw an answer to this posted here.  The answer is no, the 
performance couldn't be much different from that of a coil wound with 
dopper.  Copper loss in the secondary is so much less than the power 
lost in streamers that once they formed almost all the power would be 
dissipated in them as usual.
