A telecommunications tower, like any truss, has node points that are its strongest areas. It is best to apply any forces in the vicinity of these points, as this minimizes the risk of localized damage to the structure. This is important in practice when installing additional guy wires, securing ropes during the rotational erection of the tower, and when selecting anchor points for antenna booms. A node is a point on the main edge tube where the horizontal and diagonal truss members converge.
