[TowerTalk] Open wire measurments

[Máximo EA1DDO_HK1H]

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.

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 using Axigen Free Mail Server:
