How do we reduce wind load in base station antennas?
To reduce wind load in base station antenna designs, the key is to delay flow separation and reduce wake. This equation can be simplified, as only the third term on each side is related to pressure drag. Furthermore, force is related to pressure: How do we reduce wind load for base station antennas?
How to calculate wind load of antenna?
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 shape is different, the maximum value may be at any angle. I
What is wind load based on?
wind load as a function of the length-to-width ratio of the antenna. For wind loads based on win on on Base Station Antenna Standards by NGMN AllianceABOUT KATHREINKathrein is a leading internation l specialist for reliable, high- quality communication technologies.We ar
Which wind direction should be considered in a base station antenna?
In aerospace and automotive industries, only unidirectional wind in the frontal direction is of concern. In the world of base station antennas, wind direction is unpredictable. Therefore, we must consider 360 degrees of wind load. Wind force on an object is complex, with drag force being the key component.
