Question:
With an antenna like a 4 square you simply "float" the other three
verticals in order to get them out of the picture while you're tuning
the 4th vertical. These three floating verticals are almost exactly
resonant with the one you're interested in. Why is it these near
field resonant structures don't matter in this case but are highly
unwanted in the case of guy wires?
