After extremely bad experiences with cable Germany (chaotic service) we changed to DVB-T. We tried several indoor antennas with consistently poor results. Then I found at Amazon numerous positive reviews for the outdoor antenna BZD 40 from Kathrein. We decided to buy. The antenna is quite small, unobtrusive and super easy to install. It was mounted on the wall approximately 3 m height. After installation, without any direction correction, immediately surrendered receiving values of nearly 100% for all 26 channels received. Even in bad weather (thunderstorms) There were no deteriorations of the reception. We are after 5 weeks working very satisfied and have the positive reviews continue to add anything except: "just great"
