I had a stick of 120' of Rohn 25 guyed every 30' up with Philly. A
large, previously thought healthy maple went to ground due to wind &
rain. The maple took out the eastern guys at 30' and 60'. The tower
remained up with a serious wow just below the 60' level. Seemed fairly
stable and I gave transient thought to going up it to save the antennae
on top. I discussed this situation with a group of experienced tower
fellows and promptly dropped the tower without another thought of trying
to "save" the antennae.
I was also surprised that the tower would have remained upright with
such a force applied but , in the cause for safety, it really didn't
matter. I've been harvesting the sections when time allows for scrap-
not for rebuilding purposes. I would not trust any of these sections to
be good after the hula dance that they were subjected to.
73 and I remain,
