The choice of frequency is, in fact, governed, in part, by an ionospheric
window that extends from about 10 meters to about 10 cm wavelength.
Atmospheric conditions may extend the lower wavelength to as much as 30 m or
more. I think Grote Reber, before his passing, worked at 160 meters.
Hope this helps (hope I'm right).
