I should add that the 'true' Moxon that you refer to is  about 3/8 by  1/8 
waves. I am used to the end loaded shorter versions here: 1/4 by 1/8.
 
I have a fractal version that is 1/8 by 1/8 waves.

Sorry Dave; the Moxon phasing is caused by the 1/8 wave separation. It is  
a close-spaced 2 el Yagi.
 
The Hex is a Moxon with W bendbacks of the driven and parisitic.
 
The virtue of the Moxon is that it fits in a  form factor that  is  about 
1/4 wave by 1/8 wave, as opposed to 1/2 wave by 1/8 wave. This  makes it 
practical to support as wires as opposed to tubes. The Hex shrinks  the long 
extent a bit more.
 
Best,

Yes.  A true Moxon has less forward gain (only slightly so  on a proper 
design) and less front-to-side than a normal yagi, but it  has a really 
deep notch off the back.  The statement that a Moxon  is nothing more 
than a 2 element yagi with bent ends is simply false.  There is a phasing 
component that is not purely  parasitic.
