That strong and rugged mast is placed on a swiveling bearing in the mast base which must be rooted in a concrete foundation. The standard high is 10 m with three stainless steel span ropes. An instrument carrier at the top for two wind sensors is standard. Other instrument carriers can be delivered optional. The mast will be delivered in segments with flanges. To service the wind sensors, at the top of the mast, the mast can be swiveling down by using counterweights (option /CW) for easy bending down. The whole mast is made from aluminum and the screws are made from stainless steel. The surface can be delivered anodized or lacquered e.g. as option security painted in red and white. (option /RW)
The mast base must be placed into a concrete foundation. Further options are an obstruction light (option /OL) at the top of the mast and the lightning protection (option /LP) which must be used together with a suitable grounding of the mast according to the local conditions.
