To state something pretty obvious, that range of frequencies, or rather wavelengths, covers antenna technology markedly different at either end of the spectrum. Antenna gain is dependent on (among other things) frequency selectivity over a narrow range. In fact it is a huge challenge to make antennae that can operate with any gain across an octave band of frequencies, much less across the many octaves as he describes. And the behavior of electromagnetic energy at very short wave lengths such as at the 47 Ghz end, requires quasi optical techniques that would be totally ineffective at 700Mhz. Now he may be describing an invention based on a principle that works equally well over any small range of frequencies anywhere in that larger range, rather than covering the whole range. But even so, physics is physics. I like Bud's thought....maybe it is a prank being played just to get us all discussing it, theres just enough engineering lingo sprinkled around there to make you wonder...
