Actually, this is already a very old topic. The company Sirio is rightly criticized again and again, because it declares this model as a station antenna and that is unfortunately not correct. In fact, it is a mobile antenna, which is only to operate when parking. There are now massively broken antennas, so that their owners call them, among other things, "GayMaster".My GM has survived a few high wind events. Not sure, but I think it's close to 5-6 years old.
My Gain-Master has been up for over 4 years and is most certainly a [base] station antenna.it declares this model as a station antenna and that is unfortunately not correct.
