In this plan, an octagonal cross-section is used, and the general endurance against wind and natural factors, as well as the total weight of the base, have been desired. In this design, the structure is mostly assembled by the welding process, which can be used to improve the execution performance and also to increase the endurance of the work, if you know the performance and output of the base, the flange connection in each joint can be used instead of welding.
