But of course the statement is true. 1W ERP from a dummy load inside a Faraday screeen inside lead-lined container will also radiate as well as 1W ERP from a full sized dipole. The key word is Radiated (the R in ERP). You will need an awful lot of megawatts (gigawatts?) to get 1W ERP from such a dummy load but once that watt is radiated there is no difference.
