B&R "Spark discharge", page 284:
"6.11.1. Negative leader.

it`s more difficult to make the breakdown by the negative voltage, we
need higher voltages to do that."

i mean the other - "you don`t really need any ionization or streamer
activity at all" near the antenna, to distort the fields, as a result
of charging the nearest objects.

how can you see anything, if you eventually short C2 with 1M of scope
input resistance?
how can you see anything, if C2 is about 487805 times bigger than C3?

definitely not only at the leader head, but instead all area of the
"jacket" of charge - all this charge is screening the head and in the
end causes the leader to stop.
