I have been using SteppIR since about 2004.
W4TV pretty much hit the gain question.
Pros:
* Multi monobanders with no interaction from other elements as they
don't exist.
* Ability to use bidirectional mode
* Ability to switch 180 degrees in seconds.
* Reduced rain and snow static as the elements are encased in tubes.
* Ability to tune the antenna to your needs on the fly. I asked
SteppIR for a 20m build that would maximize forward gain but
minimize F/B.
* Shorter elements with the folded element loops with a very tiny drop
off in performance, if you are looking at the BIGGER versions.
* Ability to retract the elements in bad weather, lightning
* Add yours here
Cons:
* No instant band changes with the steppir motors
* Heavy
* Moving mechanical parts. Shafts have broken.
* Tapes can have problems going through the turns/sweeps
* If not assembled properly water can get in to the tubes and create
issues in area with moisture and freezing.
* Requires a controller and extra wiring
I love them. I think they work great. I have some issues. One caused
by me and a cable getting damaged and one from SteppIR using a component
that was not UV protected which caused the boots that held the tubes on
to rot. Replaced free by SteppIR and one shaft failure.

I discovered a few years ago that you can't ask any questions where an honest
answer might be construed as a criticism on the SteppIR forums. The dialog
degenerates into something resembling the useless old alt.advocacy newsgroups.
My question: With a SteppIR beam, what is the tradeoff of the fixed element
spacing on gain and pattern? Especially compared to the
multi-yagis-on-one-boom high end multiband antennas. You're pretty much in the
same territory price-wise.
