It turns out to be somewhat less than twice the impedance of the lines
taken separately. Double 75 coax used as a balanced feedline was
called 130 or 135 ohm at AT&T. Someone know the reasons why?
(Was used a lot in baseband analog video where pickup of hum noise was
a real problem. They've gone digital now, of course...)
