But what was the basis for his recommendation?

Is there some practical detail that creates a huge problem?

or is it just the simplicity of getting the right element current 
when there's no matching network at the feedpoint, and the "current 
at the end of the coax == current in the element"

or it allows you to leverage the decades of experience with AM 
directional arrays


Sometimes, it pays to revisit the underlying assumptions behind the 
traditional wisdom.
