Normally designing an antenna is a compromise between the SWR curve and the
F/B and gain is basically a function of boom length. Since the SteppIR
adjusts at various frequency increments, I would guess that it always close
to the optimum setting for gain, F/B and SWR.

I think I recall the Steppir people telling us that the max fwd gain vs
lowest
vswr may (probably?} occur at different element lengths.
Perhaps someone (Steppir?) can tell us how much variance in gain there is
when
changing
the factory settings to user determined vswr settings.
