When I said it "doesn't work well", I meant that it doesn't
work like a single predictable dipole. If the 40m dipole
soaks up a lot of the RF energy on 15m, the radiation pattern
will not be the predictable figure-8 broadside 1/2WL dipole
pattern. It may be more of a multi-lobed cloverleaf radiation
pattern. If one aims a 40m dipole broadside to the desired
contact point and uses it on 15m, it "doesn't work well".
