Harry:

Here is the general rule of thumb way to approach this requirement. With the booms aligned, each antenna only "sees" a
lower frequency (larger) antenna. So start at the top with the 2 meter antenna. It needs to be a half wavelength at 2
(~40 inches) from the next thing. And so on to the others. The 6 meter should be about 100 inches from the tribander,
and the tribander doesn't care. It looks mechanically clumsy, but putting the 2 meter half way between the tribander on
the bottom and the six meter on top with the 6 and triband 100 inches apart is close to the best compact arrangement.

Because that's the assembly I have here.

Seems to work quite nicely --- compared to leaving it stacked in the
corner of the garage while anguishing over finding The Perfect Solution.

I knew I had a better JPEG of it around here somewhe

From the top - down: CC A50-3S , an old CC 215WB , and the CC A3S.
That's a home-brew 2M vertical on the forward boom of the A3S.

Sigh... It all comes down in a couple of months.
Moving to a new Grid Square....
