Addressing your first plot from 3 to 30 MHz: Your worst case return loss
(RT) shows roughly 4 dB at the low end and pretty much 5 dB for the rest of
the plot. At low points of the RT I'd expect something considerably less
than that. If it were me, I'd start looking for loss in the system. It'd
start with the 49:1 and use a 9:1 instead. Remember, system loss will make
otherwise marginal to bad systems "look good" in both SWR and RT.

Barry,
Looks like you've got some decent readings that your antenna tuner can
grapple with reasonably.
I was curious as to how you have the antenna placed. How high above your
ground is it? Do you have it horizontal or sloping?
In my 50+ years of hamming, I could only have dreamed of using a VNA
analyzer on my antennas. I love playing with wire antennas now, and the
endless fiddling with seeing immediate results with my nanoVNA.
