[RTTY] Antenna Separation Question

[Barry]

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.
