I assume you are trying to configure a 1/4WL 75 ohm piece of coax to
interface to your ~100 ohm loop. What I would do is cut it a little
longer than 1/4WL with the velocity factor taken into account. Connect
it to the antenna and trim for lowest SWR on the MFJ258B. Why bother
with an exact 1/4WL when you can trim for lowest SWR using the actual
antenna?

You're right, trimming is the easiest method to matching a delta loop.
Anyway I hope my Analyzer could help me to get 1/2 wave coax and some sections for a phasing system
