I have a 73 magazine from Sept. 1998.  There is an article  by Chip Cohen N1JR .
"Multibanding the Fracvert Half-wave."  He describes a wire vertical for 20 meters 
that can also be used on 40, 30,17,15,12, & 10.  Simple antenna:  Feed section
(vertical) is 11.8 ft,  Horizontal section 17.4 ft.  Top section (vertical) 23.6 ft.
Radials were 17.5 ft wires around the base of the vertical feed section. 
I have done many searches for HF fractal antennas on the internet.  There are 
some articles that don't require a math degree to understand.  But I get the 
feeling that any articles that gave details of the construction of one have been
removed.  I believe that Chip N1JR founded a company to develop and build 
antennas for the military and commercial interests.    I remember seeingthe 10 meter
beam article too, but good luck with googling it.
