While the mismatch may not seem ideal, you have to realized there are limitations to matching networks. In order to completely correct this type of mismatch it would require something like an impedance regulator that could constantly recorrect the changing impedance. I don't think I've seen this device in any standard radio application.


The reality is these mismatches do not cause a problem since the match is ideal at high power where it matters most. The match slowly gets worse as the as the power is reduced but that's not a problem because the simultaneous reduction in current keeps the transistors dissipation well within specs.
