I have no specific information on the stability of the balcony support in question. However, satellite dish mounts are generally designed to be stable and wind-resistant, but their actual stability may depend on the type of material used and the quality of construction. If you need further details, I recommend consulting the manufacturer's manual or contacting TechniSat customer service directly.

I can confirm that the required pavilion is 50x50cm.

40x40 or 50x50 is no problem and can withstand the wind.

The diameter is approx. 2.5 cm.
