Super fast delivery and unpacking the carton, the antenna is finely crafted, installation is simple and the excellent result because I am in a sunken place with trees that obstruct the view of the issuer. I had before a 21 elements that had too much wind resistance and often leaped tnt! This antenna with its three floors allows taking high signals, horizontal and down ...
