Why is 2" separation a problem?
There are numerous commercial Tri-band 6-2-70cm yagis that share the same 
boom....0" separation.

It is all about tuning. Plug-and-play....."out-of-the box" commercial Yagis 
closely spaced might not perform as expected, but with proper modeling and 
tuning, it can be done.
