How much DC power produced will depend upon
how close the circuit is to a commercial AM
broadcast station or stations.
the answer is: there is no DC
=...
ZERO........... if there is no rectification there is no DC.
Transmitter and receiver relation is explained by Near Field and Far Field principals.
Antenna transmitter(TX) and antenna receiver(RX) relation is explained
by SWR principals related directly to physical length of the wire corresponding to frequency of the transmitter.
( another words : physical length TX antenna must!! be giving SWR of value 1:1
!!! or close to that in the {path TX output} { transmission line e.g coax} {and antenna}.
(SWR= or< 1:1.5 is still not so bad) [/size]
Typically but not always 50 Ohm is the standard for impedances in this path.
50 Ohm is a compromise value between the best transmitting and the best receiving matching impedance ot one single antenna that must be build for Transceiver ( tx and rx in one - known as walkie talkie )

Then why should an antenna not be able to catch that electricity? What's wrong? Maybe we should omit the small capacitors (shorting it).
Antenna must first resonate
- by that we understand that the diameter of an antenna must match wavelength of electromagnetic wave of interest)
light is electromagnetic wave (EM) too. Antenna can represent quarter of the wave length of EM .
Antenna can be shortened by adding coils so than the length of the coils adds to overall physical length and antenna still looks small.
However the parameters causing antenna length matching wavelength of the EM , are related not to length of the coils wire but to electrical properties of that "extending electrical length coil"
- namely coil reactive components :
capacitive reactance and inductive reactance of that "extender"
Dielectric material can interact with electromagnetic wave ,( focusing light lenses)
So now if the wavelength of the wave is as small as visible light , we can measure length of one single photon ( = one period)
we would not be able to build antenna of 1500nm for that particular frequency of light .
So now we are dealing with resonant properties of spacial geometry.
To understand why it is nice and warm in the sunny day we need to know that photon. (any photon) if it resonates with something on its own path it gives up energy,
and that energy most likely will be converted to heat.
The higher is the wavelength of the photon in the an antenna or material acting as an antenna the higher is the energy one single period.
The more heat is than deposited on the resonating antenna.
So in sunny day everything resonates by absorbing heat from the sun and converting it to heat
The reason EM of ultraviolet light is dangerous is easy to explain:
Once we know that the higher is the frequency of the EM the higher is the energy of one single period ,(= 1 photon)
Than we have area where saturation of photons of given frequency ( wavelengths ) per square ruth value (= square area or x,y dimensions ) is our body.
And our body is simply not prepared to handle this kind of heat per square unit of measure in x/y dimension
Our receptors might not feel ( receive) information that than will activate protective mechanisms preventing overheating of our body cells and/ or creating interaction not properly handled
the reason I got bad in my health right after Lithuania Experiment and Colman Experiment is most likely activity of photons of waves in the wavelength shorter than UV
And these would be:
- X-ray
-Gamma
With the last two EM ( electromagnetic waves)
gamma is the "strongest one" - ( gush I do not like the wording I used to describe it it.
It is explanation in the format directed to Idiots.)
The wavelength of X-rays is usually written in eV ( electronVolts) however could be expressed in physical length of 1 period or in Hz.
It is just the matter of convenience.
In that convenience we point fact that the main factor of that short EM is its energy and possibly interaction of that energy (per period) with the matter.
