[TowerTalk] Rotator and Beam advice requested

[Jim Cassidy]

They recommend retracting the STEPP IR elements so they will not sustain damage if the elements break.  That way only the elements would be damaged.  I think they actually do pretty well in high winds anyway.

There may be some reason, but I do not know what it is.  I stayed at AI6V's
(sk) QTH in Aruba a few times and he requested that I retract the elements
of his 4 element StepIR after use. Unfortunately the elements quit extending
and the antenna has not been used in years.

I thought a StepIR had some kind of conductive flexible tape on inside of 
fiberglass.  If so, what's up with retracting elements to reduce wind load?
