But you still haven't told us what the Z reading is at the low VSWR
point, which will help us help you zero in on what's going on. :)
Also, the variation in wavelength between 1680 and 1830 is only
about 10%, so the transformation is still not a LOT different from a
half wavelength. Also, I wouldn't trust that your guess about the
electrical wavelength in coax to tell you for certain what the
antenna Z is. But the Z reading combined with the VSWR will help.
