Robin, there is only one lower frequency where radiation is not possible and that is zero radians per second. If you believe that some other frequency exists that is a threshold how would that be determined? What in nature would separate one frequency from the next so that a well defined chasm is found?
Radiation can be generated at every frequency above zero radians per second but, as you suspect, it becomes difficult to develop an efficient radiating structure at near zero. In the case of an atom, no radiation at all should be allowed, regardless of how inefficient the radiating structure unless it happens to be at one of the defined energy lines. So, if Mills' model has a structure that allows the distant E and H fields to vary in time at any rate, then it would radiate at that frequency. A non radiating structure can be shown to hold the far E and H fields constant at all frequencies. The loop carrying DC that I often use as a model is an example of a structure that does not radiate, but that is only true when continuous smooth DC flows around the loop. If for an experiment you collected the distributed charge from the perimeter of the DC loop and turned it into a single point charge in motion around the loop, radiation would be generated. This is a result of the accelerated charge in motion around the perimeter of the loop. When you spread the charge evenly however, each tiny incremental charge is accelerated and radiates into space. But, radiation is balanced out in all far field directions by the vector summation of all of the infinite incremental radiating segments.

A distant observer would see an E field that is changing direction back and forth at the rotation rate. This is exactly the behavior expected from a short dipole radiator. Unless I'm mistaken, the reason for non-radiation is that there is a lower limit to radiation as a phenomenon. It is the nature of the photon itself which imposes the restriction. Photons have certain requirements, and if the moving electron can't meet those requirements, then no photon can be constructed. The result is "trapped" energy, which can't radiate, because the requirements can't be met. Mills uses the Haus condition to explain the trapping, while I use lack of angular momentum to explain it.
