One consideration FOR the SteppIR, based on this thread and some posts

The SteppIR may fare BETTER than regular aluminum antennas in
salt-spray environments.

The copper tape itself is sealed inside the stepper housing and the
fiberglass tubes. It is exposed only to what manages to leak inside.

Although I suspect that salt spray will do something to the fiberglass
exterior, and its effect on RF performance is unclear, at least you
will not have salt spray attacking the joints between telescoping
aluminum sections and reducing conductivity at those joints.

Not at all an illogical idea that the SteppIR might be a good answer
for salt spray environments.

As with all the rest of the considerations, a little time in grade
will answer many questions.
