That's true to a point. I have used efficient homebrew antenna tuners
my entire ham radio life and wouldn't be without one. But you can get
some REALLY ugly radiation patterns from trying to use the same antenna
on several bands. The antenna may tune fine and still not be putting
your RF even close to where you want it to go. I always tried to stay
reasonably close to a half wavelength ... for example, using a 50 foot
dipole for both 20m and 40m still gives a fairly clean pattern on both
bands.

Anything worth doing is worth doing to excess.
