     Not quite that bad.  The main thing is to get the angle 
of radiation down.  There are ways of doing this with 
shorter than 1/2 wave verticals by adjusting the angle of 
the radials. But, you do need a good radial system, not just 
a few wires. By using a folded arrangement for the radiator 
its possible to get the feed point impedance up.  Low 
impedance at the feed point is a problem with short antennas 
but can be helped with devices like capacity loading hats 
that also tend to depress the radiation angle.  Lots of 
material in the literature on this.  It still takes a large 
structure to radiate decently at low frequencies.
