The final design of my 432Mhz EME antenna array was decided not to be extreme long yagi's with high gain. In stead I made the choice to use antenna's which have less then 3-meter boomlength. The boom length was chosen in order be able to construct two antenna booms from one standard aluminium length material - 6m.  

The original 4.2 wl design of DL6WU was 3.12 m length, which made it interesting to run YO, Yagi Optimizing, in order to shorten the length to less then 3 meter. The article describes the final mechanical dimensions and theoretical results of this modification.
