[TowerTalk] Wall thickness?

[n8de at thepoint.net]

Yes, those broken tips are caused by the vibration fatigue failure  
which occurs when the elements "HUM" in the wind.   Damping them  
internally (rope is sometimes used) and capping the ends (or using  
silicone seal with a tiny drain hole) usually stops that problem  
before it occurs.
