>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).
