Another point or two and then I'll shut up.

1)  The expected phase shift in a line is only achieved when the line is matched.

2)  When I was doing EME I, and everyone else I knew of, used equal length lines 
everywhere and maintained symmetry, even if it meant some lines had more loss 
than necessary.
