OK, IMO your setup, with the mast, would show a gain pattern of about 270* away from the mast peaking toward the center, and would show less gain in about 90* degrees to the back. The pattern would be sorta' egg shaped. I don't think there will be much difference, but you could check if you have the contacts in the right place. You may have to be able to turn your antenna a bit to check.

I did something similar once when I co phased two of my vertical antennas at 36' apart. I could see a difference, but I could not change directions in order to check it.

BTW, my offset is only 3' feet, but it is isolated also...you see empty space between the mast and the dipole, there is no better insolator.

I hope I made this issue clear. No back to the A/P and the Merlin. This is difficult, because I didn't model the Merlin with a mast, and now everything will have to change.
