Basically, the more separation, the better.
A friend has a D3W mounted 10 ft above his TH7,
parallel to the Yagi elements, with no apparent interaction.
Placing a dipole (or beam) at 90 degrees to another
does NOT guarantee a lack of interaction. The boom
of the Yagi is a conductor, often end loaded by the
parasitic elements, and is NOT invisible to RF.
