In an article in a recent issue of Microwaves & RF magazine, Jack
Browne makes the following statement:
Frequency plays a part in any link budget, especially for longer links,
since long-distance links require the LONGER PROPAGATION DISTANCES of
larger-wave-length, lower-frequency signals rather than
smaller-wavelength, higher-frequency signals.
(emphasis mine).
I was miffed initially by this statement since, as far as I know, there
is nothing inherent in wavelength that impacts how RF waves travel
through space.
But I guess this was just a way (a confusing one, IMO) of referring to
the wavelength dependency of antenna aperture, as explained nicely
in this article on the Friis equation?
