This seems to be the same old JFET source follower
that has been around forever, except it uses two FET's in
parallel.  Why not 3 or 4?

I completely fail to see why this amp would be superior to similar
designs already being widely used.  Can someone enlighten me as to
what is special about it, if anything?

My approach to the amplifier noise issue is to abandon 102 inch CB 
whips, however elegant, and instead use 30 foot monopoles with top 
loading, as a brute force tool.  MUCH more signal coming in, in the 
first place.
