Besides the obvious of seeing if the antenna really performs to the
manufacture's claims, you can see how the antenna will work at your
station.  You can see what the pattern will be at your tower height and
and how it interacts with other antennas on the tower. You can even see
how two or more tribanders will work in a stack if you wish to add
additional antennas to your station. Modeling software (NEC2) is
inexpensive, even free in some cases, and it can save you many labor hours
experimenting with different station configurations.

What is the purpose of modeling tri-banders, like Steps, etc. Is it just
to compare antennas before purchasing one? If I have a Step up, why would
I want to model it?

Sure not gonna be moving elements around for more gain or F/B.

Just curious.  73
