Since I'm planning an antenna installation I did some modeling of a
Cushcraft D-40 (half a 402CD) at 60 feet over poor ground (Diel Const
= 10, Cond = 2 ... sandy Florida soil) vs a four square with 60
on/in ground radials per element. The loaded dipole was about 2 dB
better (at the same take off angle) than the four square (and a full
size dipole would have been even better).
The difference is enough for me to decide the four square isn't worth
the effort on 40. One of the common loaded/shortened two element yagis
looks the winner unless one is on an ocean beach.
