This prevents any other tall structure of building from manipulating the wind's direction and affecting the wind vane's reading. The free-spinning directional pointer has an aerodynamic shape that is wider (or thicker) on the back end of the pointer, and narrow (thinner) toward the head of the arrow, similar to that of an airplane wing. This means that there is free movement of wind, especially around the vertical axis of the structure. Rate!
