I don't know what "optimum" spacing would be, or even if it is necessary
to adjust the spacing but as all elements are active I would think it
work for any lengths between short, loaded verticals all the way up to
5/8 wave length verticals. Not just for a 4 square either. A series of
verticals in a line, two parallel lines, or a matrix of even 9 elements
theoretically would work just fine.
I'd bet that such arrays actually exist ... some where.
