So....,does anyone have any plans for a 4:1 air core balun for feeding
450 ladder from a tuner that you have actually tested and used that
and it shows close to a 1.1:a SWR when presented with a 200 ohm load?

Why not just use a(n electrical) half wave loop of coax if you are only using
it on 10metres? Or even just a Pawsey stub for a balun and match elsewhere.
You can do a lot of (single band) matching with just a quarter wave of open
wire line with shorts/open circuits and taps.
