Subject: [Antennas] Beam spacing

I want to stack a M2 2M9 2M beam (14' 6" boom) above a M2 6M7JHV 6M beam 
(30' 8" boom).  What is the closest I can space them without any significant

interaction?  Also, the 2M and 6M beams will be above a 3 element Stepp-IR 
with the 30/40 adder.  I am not concerned with the Stepp-IR interfering with

6M7JHV as I can retract the elements on the Stepp-IR (no 6M passive element)

when using the 6M7.  However, I am concerned with the 6M7JHV interacting 
with the Stepp-IR on 10-40M.  I have a 14' of available mast.  Are there any

recommendations for spacing the three beams or am I being too ambitious?
