Could be true. I also should have added that the 14 awg wire has some
insulation and, I don't know if this matter, is twister multiwire. I don't
remember what the wire is called but it is used as "hook-up" wire in equipment.
The "unbalanced network analyzer" is probably of stronger influence but I just
made it to see roughly where it was. It really was not of importance for me as
I didn't know the exact feedpoint impedance and was planning to use a tuner
anyhow.
I didn't think the balanced to unbalanced could be of that much importance as
the feeder was several (~10) d - d distances above ground when tested.

My calculation of that line works out to 579 ohms.
Something doesn't add up here. Probably explained
by trying to measure a balanced line with an
unbalanced network analyzer. Or using a balun
you haven't calibrated out.
