CableTronix 12-Input Passive Headend Combiner With Test Port (CTHC-12G)

CableTronix CTHC-12G 12-Input Passive Headend Combiner

Best For

Headend installers combining RF outputs from up to 12 modulators or processors into a private cable distribution system.

Why Choose CableTronix CTHC-12G?

This passive combiner brings multiple RF sources to one output and fits a standard 19-inch rack. Its separate test port allows system monitoring without using the main output connection.

Key Benefits

• 12 inputs accommodate multiple headend RF sources.
• 40–1000 MHz operating bandwidth supports the specified RF distribution range.
• A -20 dB test port provides a monitoring connection.
• 19-inch rack mounting integrates with headend equipment.

Who Should Buy CTHC-12G?

Choose this model for a 75-ohm headend that requires passive combining. Account for its insertion loss when designing system levels; it combines signals rather than providing amplification.
