The TRedess Fourth Series Low Power is a family of air cooled UHF and VHF Transmitters, Translators/Transposers and Gap Fillers (for DTT and DAB+), which bring together high-quality performance, modularity, flexibility, outstanding compactness and smart installation and operation, thanks to its all-in-a-box standalone architecture (exciter and amplifier on the same chassis). TRedess Fourth Series Low Power provides output power ranges up to 400W (500W for ATSC 1.0) and covers the DVB-T/T2, ISDB-T/Tb and ATSC 1.0/3.0 standards, for both MFN and SFN networks.

Product Specs

High level of compactness:
