Now that the elements design seem to be established, I was wondering if anyone had modeled the impact of nesting 4SQ structures around each other. I was wondering what the impact of having a 80m 4SQ inside a 160 4SQ would be.
Although I have plenty of land, I'd hate to run large feed and control lines all over the place unless I have to. Would be great to have "concentric" 4SQs with the switching and feeding all in the center. Was thinking of having a 45 deg offset between the inner and outer structures. This looks so much neater, but does it work?
Along the same line, what is the impact of having a 90' tower with a bunch of beams in the center of a 4SQ.
I am really looking for actual computer models or first-hand experience. I am familiar with the tower suspended array in the ARRL Antenna Book and I am sure it works, but the real question is how much of a compromise this is and if it is worth it.
