That is true...to a crude first approximation. The thickness of the antenna as
a function of frequency and antenna length is not so linear. The actual
calculation goes:
Calculate the THEORETICAL length as a submultiple of the wavelength.
Then do the finagle fatness factor for element thickness.

-While on the subject of antennas, having built a couple of Jimīs plumber
-delights, could this antenna design in principle be used for any bands or
-can it only be built for center frequencies within the VHF-band?

-Every antenna I have seen can be built to any frequency. Do it by adjusting
-the dimensions of the antenna inversely proportional to the frequency. for
-example if you want the antenna to work at twice the frequency then the
-dimensions should be half. Likewise if you want to use the antenna at half
-the frequency then the dimensions should be doubled.
