I agree that carbon and fine metal powder has been found to be the source
in
many cases, but it does not apply to this case.
The guy wires were very high up on the tower, some at 200 ft level, 400
ft,
and 600 ft. There was no carbon this high up as the engineer who actually
lived with his family in a home next to the tower base (he maintained the
transmitter in the base as well) used to climb the tower to replace
lights
and reported nothing unusual in the form of metal. This tower ws on a 900
ft high hill area of solid quartzite though. Possible peizo connection?
These balls would get large, then move from the V area sometimes finding
and
following the power lines. In one case they came thru a wall into their
home area and scared the entire family who was watching TV?
After the tower was regrounded due to lightning problems, it all stopped.
