It doesn't matter. Precision doesn't come into it any more or less

A random wire is already full of nulls and nodes. Much easier to
phase vertical omnis.

No, if one antenna isn't hearing the signal you want to eliminate, the
job is done for you. If it is hearing it, you phase it away with the
other antenna.

Nothing in the operation changes. You diddle the knobs the same way
in either case, and respond the same way.

The ANC-4 doesn't care where the signal comes from, just that it's
present.

Very imprecise and technically minimalist.
