I found significant interaction between a 40 meter rotatable dipole
and a 40 meter 2-el beam whose centers were 65 feet apart, on a N-S
line. Rotating the Dipole significantly altered the SWR of the Yagi.
Pointing the end of the dipole at the second tower had near-minimum
impact (pointing the dipole to be perpendicular to the beam's boom
was slightly less impacting, but that meant moving the dipole when
I moved the beam).
Since the beam was new and the dipole was old, the dipole was removed.
