Chip, how does the fractal version "play" compared to larger  versions?

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.
