I did a fairly detailed computer model study of these two antennae, looking at
gain in particular. You can read it at http://www.k6if.com/ .
My summary was that even with fixed element spacing, the 4 element SteppIR
delivers gain approximating that of a well designed 5 element monobander on 10
and 15 meters, and that it is consistently better than the C-31 by a small
amount.
