I don't believe that it has anything to do with whether or not a match can be
reached. Some SWRs are simply too difficult to measure accurately, even with an
error-corrected network analyzer. For near ideal reactances or very high or
very low SWR, reflection measurements are inappropriate.
Some of what you say is true, but has nothing to do with the problem.
Soapbox comment: Personally, I would (and do) rather use Heliax before I would
ever use ladder line.

The results almost totally depend on the length of the ladder line. At
certain lengths, it will act as an impedance transformer and could load
your 80m dipole quite well. An 80m dipole on 160 will have a low
impedance at the feed point. A quarter wave of ladder line will
transform that
First, this is a curiosity question about KAT500 utility only. I don’t intend
to use my antenna on 160 meters.
I use the KAT500 with my 80-meter dipole fed by ladder line and a 4:1 Balun to
Coax for last 20 feet. This antenna works excellently in concert with the
KAT500 for 80, 40, and 30

Feed point Z's:
Guys, read what he wrote, not what you think he wrote.
He had a question about the operation of the metering in the KAT500, he wasn't
looking for advice on antenna design or on the use of ladder line.
If he wants that he can read my paper here:

By all means DO read and STUDY it -- it's a GREAT piece of work.

Wes…
Thanks, you are exactly right. My curiosity is about what the KAT500 was doing
and the value of the BYPASS SWR versus the values I saw of the Tuned (or, not
tuned) SWR.
Dick’s answer was right on and satisfied all my curiosity needs.
Though thanks to all that took the time to write
