My basic problem was that I grew myself a new DVB-T2 TV from Samsung and had joined an active indoor antenna without its own power supply at the other end. Samsung amplifies the antenna signal is not therefore had to be purchased a power inserter. Dear it would have been like it, that instead of the power supply would be to connect via USB possible. However, I turn a blind eye on the price. Especially because this set does exactly what it should: the antenna cable is placed under tension and thus enhances the antenna. The tuning course brought many more channels. You can see the effects in operation relatively simple test by subtracting the AC plug and calling stations who have a weaker signal. The power supply can be heard even humming the way, so I can forgive a full five stars.
