[TowerTalk] Stacked Yagis on Tower Legs

[Larry K4AB]

Is there any advantage or disadvantage to stacking Yagis
on the same tower leg as opposed to mounting one Yagi on
one leg, and the second Yagi on the opposite leg?

Either electrically or mechanically.

I recall some discussion on this topic before, but am unable
to locate it in the archives.  Thanks.
