According to Tom (don't quote me on this) in a previous note a while back, its 
to remove the pvc insulators from the elements (except for the driven 
element(s) of
course) and attach them directly to the boom.

Next time my antenna's are down I will probably remove the insulators.  Theres 
of wind here and static is a problem.  Not sure how effective it will be since 
driven element will still be insulated. wrote:
