title: Comment I on "Generation of focused, nonspherically decaying pulses of electromagnetic radiation"
abstract: Superluminally moving charge distributions of the type considered by Ardavan commonly occur inside waveguides and the radiation emitted by such sources is well known. The application of standard antenna theory shows that Ardavan has overestimated the intensity from typical pulsars by a factor exceeding 10(9).
