To those of you who have QST libraries.... look at the pre-WW2 schemes
for feeding beams with open line.... our fathers and grandfathers were no 
dummies....

At the antenna end of the open line you feed a fixed loop under the beam, 
and the beam then has a close spaced loop right above it... inductive 
coupling - and no problem with twisting feedlines....

As the proverb goes, "nothing new under the sun"....
