Indeed, all the interest of the thing..., hence my question.
But I wonder also about the QRM pick-up along this vertical segment...
I will have the answer in two weeks.

Why would QRM be a problem ? The beter the antenna the more signal it
will
pick up. Maybe you ment QRN (noise) instead of M (undesired radio
signals)
?

No ! I speak of QRM, made made, due to vertical segment (vertical polarized
I believed) that, i thougth, 'd pick up more QRM, in the same way as a
vertical antenna coupled to a dipole tight horizontally e.g..
But in this case it doesn't as this is a common-mode choke balun ; there is
no RF radiation form the coax.
In all cases I will see the result in the field very soon, adn could
appreciate both designs (dipole vs. windom).
