Wind loads are crucial in the communication towers design since they are tall and slender. With climate change bringing more storms and higher wind speeds, it is more crucial to research the finest tower structure that withstands such conditions with the least life cycle cost.
Performance factors aside, antennas with better frontal loading design and lesser weight will decrease overall tower weight and wind load issues. Base station antennas add load to the towers not only due to their mass, but also in the form of additional dynamic loading caused by the wind.
