Since I've installed several months ago, he has often rained and snowed a bit (Paris region), but I never lost the satellite signal, which happened at earlier, despite a carefully pointed parable (electronic pointer ). Only small negative remark but not affecting the grade: The plastic cover had an imperfect rounded during manufacture or storage, and it is not very elegant to see up close (something that happens only when I go on the roof, 9 meters from ground !!!). A proven effective, recommended purchase, then.
