Another consideration -- mortar holding the chimney bricks/stones
deteriorates with time. And it's not all that strong in the first place.
Every time there is a minor earthquake here in the Seattle area tops of few
chimneys fall off, breaking just above the roof line where lateral support
no longer exists. Last thing you want is more stress at that point from an
antenna mast loading it in a windstorm (foto)--->
