My half wave vertical on 40m was not fed against the ground screen anyway,
the radials were just underneath.
But even fed against that ground screen would not change anything, there is
no current flowing into that ground connection, current is zero at the end
of a dipole.

Again, a 1/2 dipole can be fed in the center or at one end, it is still a
dipole and behaves identical.
A J-pole is another good example of that 1/2 wave vertical dipole.

wave vertical on 40m which was questioned about.>>>

No, the question had to do with one half wave length DIPOLEs,
vertically and horizontally polarized.   They may be symmetric or
asymmetric but a DIpole has two poles right? 

 a conductor fed at the end (base fed vertically polarized in this case)
that is 1/2 wave length against a ground screen is not a DIpole, but it IS
180 degrees long (tall) for some frequency.
