GTC250 has one FM input, four VHF/UHF inputs, one RF output and one -20dB RF output test port. For DVB-T signals at PAL-B/G, VHF channel has 7MHz bandwidth and UHF channel has 8MHz bandwidth,  it is better to convert VHF channel to VHF channel and UHF to UHF channel only, where 8MHz DVB-T UHF channel to 7MHz DVB-T VHF channel may have contents loss problem.

The main contents of any mini headend are coming from satellites, internet, terrestrial TV and local cameras. Mini-head should select the wanted video from satellite and internet, mux the selected video in the new TS. Since more and more smart TVs can receive digital QAM RF signals directly, it makes more senses for commercial TV operators to convert DVB-S/S2 to QAM, convert IP to QAM and convert local cameras to QAM.  Anyway, local terrestrial TV is always popular for its contents next to subscribers. The combined QAM RF can be easily distributed over coaxial (or fiber) cable in any residential buildings at an economical way, broadcasting SD and HD videos without extra STB before smart TV.
