definitely at a 90. The 40 could and probably will interact, potentially a
significant amount, with the 15 and contrary to some beliefs and statements
"it doesn't interact because my SWR is fine" it can impact the FB seriously
before touching the SWR. It might also screw with 17 meters as well if
inline.
Having had a dipole turned 90° to the other antennas (on a rotating tower) I
can say its not difficult to remember that its off as such - and since it is
bidirectional you don't have to worry about going 90 one way vs. another.

Aligned with boom gives less interaction, but then you have to remember
that you are 90 degrees off on 40.

Which is best for mounting a 40 meter rotatable dipole above a Tri bander.
Same direction as the boom or cross ways to the boom?
