I've made my own test about a month ago with DVB-T2. First try didn't work because I was using the roof antenna (no T2-channels found, T(1)-channels yes). So I've built my own antenna using a coax-cable. Worked. Found all DVB-T2 channels in southern Bavaria, could watch the free channels, for the encrypted ones I didn't hava a smartcard.
Tested for 2hours with no problems using a LG 49UF850V (similar to 49UF8509)
