It certainly moves a little, but not enough to lose satellite internet,
for which the accuracy has to be high.
During/after moderate gusts it seems to vibrate back to its original
position (there's a little bit of 'slop' in the motor gearing, I think,
and the combination of chimney mounting (steel lashing wires) and mast
isn't quite 100% rigid.
I don't think you could get absolute rigidity.
