    Would anyone have a copy of an article from either 73 or CQ magazine somewhere around the 90's which contained an article on how to construct a Fractal Quad antenna for 10 metres. The design was based on work done by Nathan Coen N1IR.

    N1IR's original article is no longer available on the fractalantennas.com site.
    An explanation and descrpition with dimensions of one side is at http://www.fredspinner.com/W0FMS/fractant/

    Anecdotal reports have fractal antennas not doing better and sometimes not as well as as well as more conventional ones of the same size. See

    Serious studies indicate these reports are based on physical realities. For example, see
