When searching for a powerful DVB-T antenna has addressed me as the first compact, low-profile design of the product from Kathrein. The performance also impressed, so I decided to buy it. The amplifier of the antenna comes with supply voltages 5-25 volts cope, he can be considered a stranger to dine from the DVB-T receiver and does not need its own power supply. The potential gain is between 15 and 18 dB. The installation is very simple, the antenna foot is both left and right can strike, so that the antenna is easy to align. The reception is so in my foyer (Krefeld) really very good. Therefore, I can really recommend without restrictions.
