How precisely must the two scalar units be aligned to create a scalar field?

There’s no alignment requirement. The antenna in the lids are flattened spheroid emitters. Meaning the signal is broadcast nearly in all directions.
There are only two major considerations:
1)Don’t have the coils inside the field, so aiming the lids towards each other makes this simple.
2)Have the correct tuning frequency in use.
That’s all there is to it. You can have the boxes sideways, upside down, even without a link cable (albeit short distance) and still establish a scalar field.
