The DT-722 is a combiner with 4 inputs and an output designed to mix output RF signals of COFDM modulators and transmodulators with DTT channels available in the area.

The system provides an amplified output of 130 dBµV (+22 dBm) frequently required in SMATV systems.

This is a solution of higher quality than those that often use Z connections, given that preserves better the original quality and maintains lower noise levels.
