Put all the elements on the same boom. That's what I have.
My antenna is a three element tribander with a separate WARC triband driven
element on the same boom. Completely separate feedpoints of course.
The next model up from mine is the same but has 2 elements for the WARC bands.
As to how the antennas on the same boom interact, I don't really know. I do
know that the antenna works just fine and that I am very happy with it.
Try it. It saves on weight and wind loading on the tower. It looks neat as
well.
