Were these LARGE dipoles or the size of the DB224 dipoles?
(sounds like the large dipoles if they mounted to the tower itself)

What I saw were 4 folded dipoles, but only two high. Each pair consisted
of two folded dipoles mounted on opposite sides of the tower at the same
height. The spacing appeared to be about the equivalent of one folded
