DC applied to an antenna no doubt creates virtual photons.
My statements should be considered to exclude such virtual
photons. They are meant to include only detectable photons
coherent with the frequency of the driving signal capable
of propagation through free space which are emitted by the
acceleration/deceleration of free electrons in a copper
wire antenna. (Contexts nowadays are sure complicated.)

You must be assuming delectable photons.

Mine does. Like I said, yours probably needs batteries, or perhaps it
is suffering a dimbulb behind the on/off switch.

With a field mill or a moving coil of wire?

At last a truism, arguably. ;-)

Say Jim, what is the frequency of virtual photons?

Are you asking me what's "nu"? :-)

I always say it's c over lambda. For photons it's E/h.

You can be the local expert on virtual photons if you want, Cecil. I'm
only on a need to know basis with them.

I understand coherent photons emitted by free electrons being
accelerated and decelerated by RF currents on a wire antenna.
I don't know much about virtual photons. I was hoping that a
physics guru would know.

A physics guru might say that if it's a photon, its frequency is E/h
unless one of the virtues of being 'virtual' is that its frequency may
or may not be equal to E/h. Perhaps it's greatest virtue might even be
that you can attribute any physical characteristic you want to it - not
unlike some of the other virtual entities. ;-)

Now there's a familiar terrain.

Hi Jim,

Are we verging on the shadow of a photon?

Only the shadow knows. It's a quantum effect.
