The telegraph model of Weber-Gauss, relying on Weber's electrodynamics, modeled instantaneous action at a distance of the electric scalar potential (Coulomb potential) manifesting as propagation of signals at c in a resistanceless wire, through the collective forces of charge carriers in the wire. Despite seeing many allusions to the notion that wireless transmission of signals at c could, similarly, be modeled with Weber's electrodynamics, I've been unable to locate such a model for, say, a simple Hertzian dipole's actions on a remote test charge.
Does such a wireless signaling model exist?
