Here's the corresponding schematic if a 4:1 unun is used instead of a
4:1 voltage balun.

There's a small *drop* in the CM driving voltage compared to a 4:1
voltage balun. If I had reversed the unun connections to put the braid
on the long leg, there would have been a small increase.

You can swap the balun connections around to make it 4:1 UnUn, but not
much changes - you still get very similar voltages at the braid
connection.
