Don,
You have to model it to get the answer. I went through a similar
exercise when I first started stacking tribanders and gettings into
SO2R with one tower. Just as an example, If my current setup were
C31XRs, it would have been a disaster with interactions between
antennas. With TH7s, it works well.
