Pete,
Perhaps something was wrong with the four square?
An eight circle of proper dimension (using only four
elements at a time) has about 4dB gain over a conventional
4-square. A nine vertical array winds up with basically the
same gain as the eight circle array (or slightly less when
losses are included). The nine square has more losses in the
feed and phasing system, there is no way around that!
My four square (using 120/240 phase) would often beat a
two-element phased array at 280 ft on 160 meters, so in my
opinion it does a good imitation of a two or three element
Yagi. An eight vertical array would have about the same gain
as two traditional four squares spaced 5/8th wave and
co-phased, or a couple dB over my 120/240 degree phase four
square. Including all losses of course.
2 dB isn't day and night to me. a cloudy day and twilight
difference. Hi hi.
