G7-144 top-mounted at 60 feet for four years.
I would watch the wobble when the wind blew and
heard the crackling. I thought the lower phasing
coil had worked loose at the studs. Not so.

at the both the top and bottom of the lower phasing
coil were missing and the outer tube was providing
very little support. The inner assembly was
holding the top portion on.
