I want to know the answer to the following question:
What induces a feedpoint to antennas nearby?
All the background I'm provided with is that "However, because of the mutual interaction between their electric and magnetic fields due to proximity, the currents in each element are not simply a function of the applied voltage (according to its driving point impedance), but depend on the currents in the other nearby elements.". Is that enough to answer the question?
Answer: no
