RACRING OF THE CANOPY DUE TO THE ADDZTIONAL HORI20NTaL WIND <br /> FORCE ON TAE ANTEPINA <br /> If you look at exposed fascia and column shroud area of the <br /> various canopy designs , Desiqn N9 presents the least "WS::Q Sail" <br /> area. <br /> 2 <br /> .I <br /> liind Sail 11rea - Canapy M 9 - 58 x 3 + 4 x 2 x 12 = 270 FT <br /> 2 2 <br /> Antenna - n r 3 = 28 . 3 FT <br /> 28 . 3 = 10. 5� <br /> 270 <br /> Hence, the dish adds 10� projzcted area to the "Smallest" <br /> canopy. This is far less the�n the safety factors of the <br /> various desifln standards th:�t apply. Therefore, it may Le <br /> safely concluded that the r:anopy will accept the additional <br /> horizontal wind load. ' <br /> � <br />
