**Note:** At Six meters the diameter of elements in terms
of wavelength starts to become large, even with heavy wire like
10 gauge. With tubing elements, an additional shortening factor
starts to become important. As elements get fat, the resonant
frequency goes down for a given length. This is not a problem on
the lower frequencies where even one inch tubing is still small
diameter relative to wavelength, but at six meters and above it
starts to become more and more significant.
