Well, I'm still getting tripped up in my terms. Not doing too well, here.

What I'm looking for is max low angle radiation comparison of the two.

The vertical, should have a far better low angle performance, although
four radials is probably inadequate to minimize ground absorbtion.

Better to s that the vertical will put out more of it's energy at low
angles. That makes a difference.

Another thing to consider is that the vertical will take a whole lot
longer to install than the dipole. Those radials can be a real pain in
the back!

The way my thinking has been shifting recently, I would suggest that
people - a lot of people - think of the radiation pattern of an antenna
as some sort of narrow blob that shoots off the thing at the "maximum
angle". Trouble is, all antennas radiate at all angles. Some just better
than others. Before condemning a dipole as not usable for DX because of
its radiation angle, we should probably compare it to the angle of that
vertical. Then look at just how many db difference there is between the
two (all else being equal).

And of course, as I have been finding out, which one does best
at any given moment (let's define best as the highest signal level at
the receiver) is going to change from moment to moment. I haven't gone
to transmitting differences yet

The inclusion of a loading coil does little or nothing to effect the
radiation efficiency.
