MikroTik/RouterBOARD SXT 5D 16dB antenna weather concern?

Hi

last night a SXT stops working.
→ strong wind, high humidity, fine drizzle / snow, about -7 degrees
→ The wind hit the back of the SXT
→ SXT-Door ist closed like in the mounting video

So you see the original draining holes (red circle) are terrible.

In future we will close this holes.

bye
