Right, something I learned from this thread. I'm asking if there are ways to be more precise with radio emissions given omnidirectional antennae in the hypothetical case where the only restrictions are Mother Nature's, sort of like the question "can you arrange magnets to produce stable levitation?" (BTW: no unless they're electromagnets.)
