There were some articles in QST 20 or 30 years ago about using lumped
element networks to broadband a dipole.  You can get a mediocre match
from 3.5 to 4 MHz using these.  I think it stays under 2:1, but never 
gets better than 1.5:1.  That may very well work OK for many users.  The 
same technique could be used for a vertical of course.  Much more 
effective that making the diameter larger.  Probably isn't going to work
for a 4 square, because it will screw up the phasing.
