Don,
So now there are two variables that you can't really do anything about.
Therefore, the 2:1 bandwidth narrows the more frequency dependent
variables there are in the matching network. There is a paper which was
written by Fano which comes to the conclusion that about 4 matching
elements is the practical limit of wideband matching. Anyway please
Google: "Fano" and I am sure you will find a lot of info if you are
interested.
See the definitive treatment of this topic by K6OIK here:

Also, a lot of other great articles by K6OIK. This guy is good.
