Over the past two days there have been questions regarding triband vs.
six meter and triband vs. shorty-forty spacing. I'll see if I can
address both questions, since I have all three of these antennas in the
same stack. I'm not an engineer, however, so all I can offer is
empirical evidence.
I am using 12-foot spacing between the tribander (TH-11, actually) and
the shorty forty (40-2CD), with the six meter beam (M2 6M7) exactly
between them, six feet above the tribander. All booms are aligned the
same and, for me, the combination works beautifully! Any interaction
between the three is not large enough for me to measure.
