The tip of the reflector on a Force-12 6L 10M yagi (EF-610) broke off
right at the rivet. The tip is 0.375" OD dia and 44.375" long and fits
into the next larger 0.50" dia section. I suspect that it vibrated until
it fatigued and then fell off. Force-12 does not mention that dampening
rope is needed in the element tips so none was installed. With such a
small diameter of 0.375", 1/4" rope would probably not fit....maybe string
would work to act as a dampener?
Has anyone had a similar case and if so what did you do to prevent the
element tip from vibrating again?
