Actually, that particular question can be answered in a theoretical sense. 
To a first order, if you know the approximate spacing of the elements, you 
can determine the maximum achievable gain and the max front to back 
ratio.  I would suspect that the SteppIR will get as close to the 
theoretical limit as any other antenna with a similar number of elements 
and made of similar materials.

Your other questions about longevity and moving parts are well taken, however.
