توضیحات:

This Standard provides the requirements for the structural design and fabrication of new and the
modification of existing structural antennas, antenna-supporting structures, mounts, structural
components, guy assemblies, insulators and foundations.
This Standard is based on limit states design. It is applicable mainly to steel structures but may
also be applied to other materials, when required, so as to provide an equivalent level of
reliability.
The appropriate standards should be referenced for structures that support antennas but that
are primarily intended for other applications, such as water towers, electrical transmission line
structures, sign support structures, buildings, bridges, etc. This Standard, however, does apply
to the calculation of effective projected areas of appurtenances (antennas, mounts, lines, etc.)
and to the serviceability limit states appropriate for structures that support antennas
