DT-722
The PROMAX DT-722 4-Input DVB-T Combiner with Single Amplified Output (50 MHz to 860 MHz) features 4 inputs and an output designed to mix output RF signals of COFDM modulators and transmodulators with available DTT channels. This method offers a higher quality than ones that utilize Z connections as the original quality is preserved and lower noise levels are included.
