To my knowledge there have not been any motor failures. There have been some
failures of the drive system components due to the break down of a
particular plastic that was used but that has cleared up and hasn't been a
problem for many months. Having said that a failure of any components up in
the air is a problem (including a balun or maybe a rivet) no mater what but
the SteppIR concept is new and prone to some growing pains. One would have
to agree it the most innovative antenna design to come along in a very long
time.

I have heard of a number of motor failures so I wonder how common this
problem is. I suspect only the manufacturer knows this answer. If the
antenna is mounted on a crankup tower repairing it may be somewhat easy,
however if it is mounted 100 to 200 feet high with other antennas on the
tower or in an H-frame like K9LTN's problematic phased array, repairing the
antenna can be a lot of work and expense. It is true that any antenna can
break and in choosing a product one should consider which one is built
stronger and less susceptible to failure, along with comparing the
electrical performance.

There are complaints of motor/mechanism failures, but they're fairly
infrequent, and, to be fair, you hear complaints about conventional
antennas with broken traps, incorrect hardware, etc. And, because
they're new and novel, the "reporting rate" on SteppIR problems is
higher than for conventional antennas (e.g. you're more likely to find
an online comment about a SteppIR problem than about a missing set of
clamps in some other antenna)
