That would only apply to an elevated antenna 1/2 wave or higher up
though..

Actually, it need not be that high. Just decoupling an antenna from a
less-than decent ground will improve its gain. The ideal height for a 20m
antenna would be about 8m. Of course if you can put it up at ANY height,
then go for the 100m plus range, but if you can afford the hardware for
that, you can also afford the hardware to stack two beams!
