That is our current model, yes.

It is believed to be a large collection of photons moving
across space.

Because the properties of this large collection of photons are
quite well described by Maxwell's equations as a radiating
electromagnetic wave consisting of a propagating electric
field and a propagating magnetic field.

At radio frequencies these fields are easily observed and
measured. (We don't have circuitry fast enough to do that
with visible light frequencies yet, but we're getting closer).
