OVERVIEW

GatesAir’s OnePower high power transmitters by ONEtastic are available in several versions with output powers ranging from 1.5kW to 20kW average DTV power, or up to 24kW peak sync with analog modulation.

The OnePower transmitter system comprises several sub-parts:

  • An exciter (dual drive is optional), with Real-Time Adaptive Pre-correction, and multiple input interface options (ASI, T2MI, ETI, EDI, IP, Satellite) and an onboard GPS / GLONASS receiver for accurate synchronization and SFN timing;
  • Several Power Amplifier modules (from 2 to 8 per rack depending on model and the output power level);
  • A control and monitoring unit, with embedded change-over system (OneLogic);
  • An innovative, high-efficiency liquid cooling system (OnePower L series).

OnePower transmitters support several digital modulation standards (DVB-T/H/T2, ISDB-T/Tb, DAB/DAB+/T-DMB, ATSC-1), as well as dual-cast analog operation (supporting PAL and NTSC).

OnePower high power transmitters incorporate innovative World-class engineering, providing unparalleled AC-to-RF efficiency, performance, ease-of-use, and low maintenance costs.
