All of the SteppIR antenna EZNEC models are available in Dan AC6LA's
great AutoEZ tool format so you can vary the element lengths. Pretty
complex models, not good as a first experience.
Here is the link to Dan's introduction and models

SteppIR beam do not have traps but they use a fixed element spacing as
mentioned in your tribander post. Has any SteppIR owner done the
modeling work to see what effect this really has?

Trapped tribanders have shorter elements, which has an effect on
pattern, and they have non-optimal element spacing for any particular
band, which again affects pattern gain.
