That's more easily said than done. One of the critical characteristics of
a small antenna is loss. And to correctly replicate loss in a scaled
antenna requires scaling the conductivity of the conductors as the square
root of the frequency. To scale to a higher frequency requires that the
conductivity be better than the original. Unless the original is made from
lead and the scale factor moderate, this wouldn't be possible.

Hi Roy

I'm curious to know why you didnt use stainless steel as an example rather
than lead as your example.
