This is certainly true for narrow the bandwidths on 12, 15, 17, 20, 30 
meters, but what about wider bandwiths such as all of 10 and 40M 
which occupy 4% of the operating frequency?  

N4ZC has two 4L wire LP's for 80M to cover 3.5 to 3.9 MHz 
(12% BW).  Maybe that could be done with a broadband dipole 
(or ladderline fed dipole) and two reflectors, one tuned to 3650 
for SSB and the other tuned to 3350 for CW.
