Bringing up a question in the back of my mind...
This is a pretty easy theoretical analysis. Does anyone have the component
values in the Comtek box? (especially a rough idea of the parasitics and Q
for the reactive components). Or, even more useful, some port to port S
parameter measurements for the 6 ports?
I have a program that will do most of the analysis for useful cases,
including looking at the effects of non-ideal radiating elements (and
positions).
