That's true. I should have anticipated someone in the world
might actually want a poorly focused pattern with shallow
nulls, or have a 4-square where the loss is so high the
mutuals are unimportant. I actually have an array like that.
It has -20dBi gain, and a wonderful pattern shape and each
feedline is fed equal power.
