I have modeled 20m and shortened 40m beam interaction and with my antennas 
and the interaction was very minimal when pointing the same direction and 
very noticeable when pointing 90 degrees apart.  The antennas in your 
example may react differently, but I would recommend trying the same 
direction first.

Theres a great  benefit from turning the antennas 90 deg off.
but Ive heard that, when you have a 40 and a 20 on the same tower, the
is never dissipated by the 90 deg offset.

Is that true?

Thinking of setting up a xm240 with a 3 or 4 el force 20 mtr monobander
abt 15 ft apart..
