Nevada County Amateur Radio Club - October 14th meeting SPECIAL GUEST SPEAKER

Our guest speaker will be Richard Wheeler, AI6RW. He has designed his own multi-band dipole, a proprietary balun that matches a dipole wire antenna.
Richard will provide a primer on baluns and a technical discussion on the design of the balun and antenna system.
There will be several Kits available for $10 each. That is below the cost if you tried to purchase the items yourself.
For those curious about the design, here is the web site to read up on the subject. http://www.wheeler.com/ai6rw/
