Not necessarily. There is no electrical advantage to packing a ton of wire
in a small space, unless the goal is a heater.
So far as I know, no one has ever answered the simple question "why does
fractal folding offer a performance advantage?".
I see two major issues that are unresolved:
1.) The data is based almost entirely on models. There are many losses not
accounted for in modeling when wires are bent at fractional wavelength
intervals. Performance could be a whole lot worse than expected in many
cases.
2.) The antennas are virtually impossible to construct.
