WIND LOAD ON ANTENNA STRUCTURES PREPARED BY: JANAK GAJJAR SD1909 Introduction Wind calculation Pressure distribution on Antenna Conclusion References Introduction Wind forces undoubtedly play a significant role in the design and operations of large steerable antennas, and the need for satisfactory estimates of these forces is becoming increasingly evident.
