>dbu is frequency dependent. .

Agree that the amount of voltage that an antenna can produce from being 
immersed in a radiated field is frequency-dependent, as well as being 
dependent on the antenna design, its physical orientation, line loss, and 
the impedance across which that voltage is developed at the point of 
measurement.

But any radiated or conducted voltage, once known, can be converted from 
units of volts to X dB with respect to that value, at that point of 
measurement.  They are just different forms of the same number. So the 
simple equations I posted earlier will be valid.

There is an equation that relates the amount of voltage at a point in a 
conducted circuit to the amount of arriving field at the antenna that it 
will take to generate that voltage.  That does include consideration of the 
frequency (plus more).
