Just getting started modelling and looking for answers to questions not

Return Loss figure shown in the SWR window?  Just ground reflection loss,
total system loss, something else?  Trying to understand why Return Loss is
greater for lower SWR curve values. e.g see this when toggling between std
and alt impedance. What is this suggesting, go with lower return loss or
lower swr curve?

An incomplete grasp of the fundamentals is admittedly likely here <g>.

So that's what you need to study.  ARRL Handbook and ARRL Antenna Book.

Those of us who understand have paid those dues. Now it's your turn to hit the books. :)

Tough love.
