The bracket keeps its promises! In my Gibertini XP100 with two LNB some forces come on even with wind. Recently there was the first really tough storm (hurricane Niklas 01.04.2015). There was no impairment of the TV signal (Good assembly) and the values changed nothing. Thus, the holder has done a very good services. When friends and family some satellite dish holders have left behind. I am glad that I chose for this sturdy design and can only recommend it.
PS: A little tip, let the antenna and mounting by a specialist company in the roof mount, then it is also true feast!
