Do base station antennas increase wind load?
Base station antennas not only add load to the towers due to their mass, but also in the form of additional dynamic loading caused by the wind. Depending on the aerodynamic efficiency of the antenna, the increased wind load can be significant. Its effects figure prominently in the design of every Andrew base station antenna.
How do you calculate wind load on an antenna?
The drag coefficient is a key component in calculating wind load on an antenna. Its value varies for each antenna shape and must be determined experimentally or with the aid of Computational Fluid Dynamic (CFD) analysis. If the drag force on an antenna is known, the antenna’s drag coefficient can be calculated using the following equation.

How to calculate lateral wind load?
al-side wind load FlateralFlateral=F w_lateral -F mast(p)On the lateral side, because the pole is not shielded by the antenna, the proportion of wind load of the pole is large. Therefore, the wind load of the entire pole needs to be subtracted mum wind load FmaximalFmaximal=F w_maximal -F mast(p1+p2)When the antenna
