Andy,
maybe you're right, see also Planck's formula
E = h f.
But then, maybe not - consider radiated power from a given antenna height and current
Prad = i^2 * 1579 ohm * (h / lambda)^2
which clearly scales with f^2.
So, in the essence of it's innermost being, "Frequency" remains a mystery ;-)
Best 73,
Markus

Frequency expressed in dB has to take the 10.LOG form, not 20.LOG
Consider P = kTB
