Personally, I can't take too seriously the manufacturer claim that "a long boom is not needed to achieve near optimum gain and front to back ratios on 20 - 10 meters since the SteppIR can control the element lengths" !!!!

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.
