As frequency is lowered from visible light, there is no reason to
believe that photons disappear when the frequency is below visible.

There is no reason to believe that they appear in the first place when
no mechanism exists for there creation,

Photons are no more created than waves are. They are simply different
manifestations of the same phenomenon.

for all quantisation theory
and experimental evidence arises from objects that are themselves
quantised and not as
multi-electrons in electric currents.

Photon behaviour has been observed at microwave frequencies. Why do you
suppose it suddenly stops, and at what frequency?

How many cycles make up your RF photon, say, at 14MHz?

Cycles of what? Take your time now. (Hint: the 'wave packet' model refers
to particles, not radiation)


How big is the photon?

GIGO. Have you forgotten already?

"The trouble with that question is essentially that the photon is a
theoretical construction which does not have any straightforward
connection either with an entity of physical reality or with anything
simple which we can imagine."
