What I find is when lower in frequency, verticals work much better
than models seem to predict. My 160-meter dipole at just over 300
feet just ties a 200-foot vertical in the best directions for the dipole,
and my 160-meter four square generally whips the daylights out of
the dipole.
On 80 meters, I've found the difference to be less.
On 40 meters, I've found a dipole at 60 or 80 feet is much better
than a vertical, at least broadside to the dipole.
I'm not sure what others have seen, but that is how they work here
when I use large ground systems under a vertical.
I would expect, based on what I see here, that on 40 meters a
good high dipole could actually be a bit better for gain than a four
square.
