For those here afflicted with innumeracy :

  The bandwidth of the (legal) CB band is approx 1.6%
  The bandwidth of the 2M amateur band is approx 2.7%

  The bandwidth of the 6M amateur band is approx 7.6%

... and, show me a "no problem", full bandwidth, 1/4 wave, vertical 2M
antenna that does not involve marketing weasel words, in-situ futzing,
and fairy dust.

I suppose you could achieve something like a full 6M Band coverage with
a folded dipole made from 2" copper pipe.
