Work is progressing on my new satellite antenna set up. I have a couple of questions for the group.

1. What would be the effective wind area for a 2 foot by 3 foot grid (BBQ)

dish?

Tricky to calculate wind loads for grills (there's a lot of interaction between the wires and it's very wind speed dependent).. most of the time you can just be conservative and assume it's a solid surface... 6 square feet for yours (if it's actually rectangular, not oval).

2. I have a WIMO helix for L Band (Model 23-2). The info says a wind load

of 200 Newtons. Does anyone know under what conditions it is 200 Newtons so I could calculate the area of it?

200N = 44lb

Nothing on the wimo.de website talks about wind speeds...Perhaps there is a DIN standard?
