Dear Fellow Ham Clubs:


We would like to invite your membership to a discussion we are hosting in
September  at the Fairfield Fire Training Center:


Join us at 7:30pm on Wednesday, September 3rd for an illuminating talk
about lightning with our own Jeff, W9NIZ.  Jeff will present a computer
generated animation of a tower strike using advanced software that produces
a time domain animation showing voltage potentials and the lightning path
through the tower into the ground field.  Jeff will discuss related topics
such as avoiding common grounding pitfalls, reducing static buildup in the
antenna system and designing a fully grounded system.  Products and
techniques ranging from using a simple balun, using exothermic welding vs.
clamps on the tower and inline surge protected coax will also be discussed.



Following the formal presentation, there will be a question and answer
period with Jeff and Joel Hallas, W1ZR, on hand to focus on techniques for
reducing the lightning current that gets into the station and dwelling.


73,


Drum
