I'm really not very technically gifted. As it many years ago about went to buy me the first indoor antenna, I naturally oriented myself to other reviews - not only here. They're all still failed quite well. And the man from the electronics store, she praised. So I bought it to me then, but also in the subsequent period I bought them again, for all sorts of occasions. Last for my mother - her apartment was difficult reception conditions. After the antenna had to be repositioned then again, the receiver is now almost flawlessly. - I think the antenna is a good German quality product.
