That's a useful tuner simulation; but **DO** remember it assumes a 
constant Q for the inductor. Here's how a real roller inductor Q 
measures at different inductance settings on different bands:

If you want to get meaningful loss results with that simulator, be 
prepared to manually change the default Q value as you change bands and 
change inductance values.
