The vertical on top should not have much effect on the installation if the

Suppose I forget the 6 meter beam (I'm not much of a 6-meter fan anyway)
and just put up a beam such as the Butternut Butterfly (although I've been
reading some not-so-nice things about that antenna so might bite the
bullet and go with something like a TA-33Jr) with a VHF gain vertical
above that?

The radials for the vertical will be 1/4 wavelength at 2 meters, or about
19 inches, and there are three of them.

How high above the beam should I space the vertical?

(The URLs you guys provided, nor anything else I've found, don't seem to
get into that...)
