If I am not wrong, you can use a "differential probe" (it is basically a
balun), or measure every wire to ground separately, then do some maths.
Someone more skilled will confirm.

Asunto: [TowerTalk] Open wire measurments
How do I make measurements on open wire feedline with my analyzer? I have a
RigExpert which has four discrete impedance settings (25,50,75, and 100 ohm).
Obviously, the connection is for unbalanced (coax) lines. A 4:1 balun would
work with window line (440 ohm), but what about open wire 600 ohm?Email sent
