I have monitored the Steppir group from the beginning and can't remember one
Stepper Motor failure and personally know six people with Steppir antennas.
Stepper Motors are just about the most reliable motor around, they are used
in the packaging industry 24 hours a day and I have never seen a failure.
Many other parts around these motors may fail but not the Stepper motors.
I think you are starting rumors- :)
Steppir Antennas may have other problems like tape snarl up's or motor
driver chips, but not the Motors.

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)
