I looked up the references and here are my comments
1 a helical is not in a state of equilibrium

of course it is, there is an equals in the equation so it must be in
'equal'ibrium according to your definition.

2 A radiator that is not a WL or multiple thereof is not in
equilibrium

my half wave radiator, and my infinitesimal dipole both have equals signs in
their equations to they must be in your state of 'equal'ibrium also!
