For beams, the desired radiation pattern is usually
more important than minimum SWR. Using EZNEC, I've
seen a 4:1 SWR yield the desired pattern where
at the minimum 1.5:1 SWR point the F:B ratio was
terrible.

I did model this antenna with EZNEC but I forgot to take
into account the fact that the wire used is insulated. I think
that screwed up the resulting antenna. Maybe? Would an
insulating jacket reduce the VF of the wire? I've accounted
for everything else, wire gauge/loss, ant height, type of
ground, etc.
