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: https://www.fars.k6ya.org/docs/Bode,Chu,Fano,Wheeler-Antenna_Q_and_Match_Bandwidth.pdf Also, a lot of other great articles by K6OIK. This guy is good. Rick N6RK _________________ Topband Reflector Archives - http://www.contesting.com/_topband
