Hi:

A month or so ago I say a PBS piece on fractals. The piece claimed that
the "technology" is used to make the antennas for cell phones.

Have any amateurs used "fractal technology" to form their antennas?

Also, I note that "they" market HDTV antennas that are about the size of a
book. Do these things work? What's inside them?

Yours,

JLG
