Dave,
Thanks for sharing your info - Considering that we have installed just
about every protective device known other then a corona brush, I am still
trying to find accurate info on them. FWIW, I fond the following at

NFPA 781 - PROPOSED STANDARD NOT ISSUED
On July 18, 1995, the Standards Council of the National Fire Protection
Association held a hearing to consider the further processing of proposed
781, Standard for
Lightning Protection Using Early Streamer Emission (ESE) Air Terminals. ESE
Air Terminals are devices which supposedly attract lightning strikes over an
extended
distance, thereby in theory, leaving a larger radius around the device safe
from damage.
