Hello, we have few SXT5 sectors installed on a tower. The owners needs parameter of WIND LOADING to calculate wind resistance. These values are not included in the specification.

Please send me a value if its known .

If you haven't yet found an answer, then I could chip in - for this size of devices wind loading calculation should not be calculated by european civil engineering code, as it will be negligible.
Even though, we are able to make approximate assumptions. :
If you look here, you can find rather precise info.
From this, I could calculate peak wind load at 27m/s of slightly below 6N for SXT Sq.
