Dave,
You didn't model it then.
You should model your complete installation, including interaction with
other antennas. (One anecdote) I do, and it prevented me from putting a 10M
beam above a 15M beam on the same mast. By modelling it (the situation), I
was able to determine that the 10M beam should be below the 15M beam. So I
did.
Remember, modelling is like system design. You must take into account all
the system requirements, not just one element (pun intended).
Visit my website for a walk through a Ham Station system design.
