Some SteppIR antennas have been up for a year or more already and have
survived high winds and ice storms, but I don't recall hearing of any lightning strikes. The antenna itself has only beryllium-copper tapes whose length is adjusted by stepper motors, the latter being pretty robust devices by all accounts. The sensitive electronics (microprocessor control unit) are in the shack rather than up on the tower, so the smart thing to do would be to disconnect and ground the control cable when not in use (after retracting the elements completely), just as one would disconnect and ground the feed line.
