EM waves by Heaviside are transverse. Now we should check if he was right.


You have confused the telegrapher's equations with propagation.


Before you recite an authority, you really need to understand them.


It is commonly known: "Heaviside said that mathematics was an experimental
science. He organised Maxwell's mathematical work into the four equations
which we now call "Maxwell's Equations".

Maxwell made the model of solid ether. The four equations by Heaviside is
rather "fluid analogy".

"Now Heaviside had the concept of the TEM Wave, which Kelvin and Preece did
not. With these two formulae, he could give a gloss of mathematical style to
his assertion that, properly treated, a slab of energy current could
propagate at the speed of light without distortion. This assertion had
massive practical implications, but Heaviside was obstructed for decades."

If radiation occurs at the end of a dipole ( which it does) it exists
only in the near field
because of its lack of spin. ie charge dissipation but without spin.
