Our quality weather vane is made in right here in NZ from a heavy duty nylon plastic/glass material, very similar to what your wheelie bins are made from, although a lot tougher.
It’s very ridged & feels almost like steel. It’s ultra-tough and 100% UV stable as you would expect for something being used in direct sunlight & NZ’s harsh weather environment.
There is a long tubular hole in the base of the bracket so you can mount on a pole like a broom handle or similar.
The un-assembled size is 42cm x 45cm high.
What is a Weather vane & how does work?
A weather vane is an instrument for showing the direction of the wind. They are typically used as an architectural ornament to the highest point of a building. Although functional, weather vanes are generally decorative, often featuring the traditional cockerel design with letters indicating the points of the compass.
The design of a vane is such that the weight is evenly distributed each end, but the surface area is unequally divided, so that the pointer can move freely on its axis. The side with the larger area is blown away from the wind direction. The pointer is therefore always on the smaller side. Most wind vanes have directional markers beneath the arrow, aligned with the geographic directions. Wind vanes, especially those with fanciful shapes, do not always show the real direction of a very gentle wind. This is because the figures do not achieve the necessary design balance: To obtain an accurate reading, the wind vane must be located well above the ground & away from buildings, trees & other objects which interfere with the true wind direction.
Changing wind direction can be meaningful when coordinated with other apparent sky conditions, enabling the user to make simple short range forecasts.
