Effective Insulation

THE question whether additional in- ~ gulators on a@ feceiving aerial will improve matters depends entirely upon whether the insulation js already as near as may be perfect. If it is, then additional insulators’ will have no effect. If it is not, then additional insulators will certainly improve the efficiency of the aerial. Clearly any signal energy, induced in the aerial by the incoming electric waves, which runs to earth owing to.faulty insulation, cannot be going into the receiver, and to that extent the efficiency of the aerial is below normal.
