This doesn't answer your details, but what I did to test the one I made
was simply to compare it to the balun in my manual roller inductor
tuner. I used a short coax jumper between the tuner and the homebrew balun.

Ok, so this morning, I went out to the shack and whipped up a balun, from a G3TXQ
design I found on the website of W5DXP.com. It is coax wrapped around a ferrite
core, with appropriate connectors in a plastic weathertight box. I used RG8X coax,
a 2.4" core, not sure exactly what mix, and 11 turns.
How do I test this device to get its properties, impedance at various
frequencies, etc?
