My TH7DXX is at 72 feet. When I had a 2 el 40 up 6 feet above it I experienced no _discernible_ negative affect on either. Surely there was some, but not noticeable.

You will almost certainly have to orient the 40 m dipole at 90 degrees to
the beam (parallel with the tri-bander boom) to avoid interaction with 15
meters. 5' separation is usually enough.

What would be an acceptable separation between a 40m rotary dipole and a
3 element beam? I can maybe go 8 ft, 7 for sure......I'm fairly certain
there would be some interaction, but would it be that critical ?
