Just for clarity, what you described is not a 4-square in the ordinary
sense. The current maximum in your conductors is many feet off the
ground. (How high was the center of the lazy vee dipoles?) A typical 4
square has the current max right at or a few feet off the ground. If
the centers were 70-100 feet, it WOULD play like a 2 element shorty
forty.
A bit of apples vs. oranges here.
73, Guy.
