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.

FREQUENCY MARGIN	From 50 MHz (C-2) to 860 MHz (C-69)

INPUTS	4 inputs Female BNC, 75 Ω impedance

RF OUTPUT	1 female BNC output, 75 Ω impedance
Maximum output level	1 channel at 130 dBµV 2 channels at 127 dBµV 4 channels at 124 dBµV 8 channels at 121 dBµV 16 channels at 118 dBµV

CONFIGURATION AND POWER SUPPLY	Through the DT-800 control and power supply unit. Control can be done remotely from to PC.
