Description
Cadco 12-1000 12-Input Passive RF Combiner 5 MHz–1 GHz Channel Hybrid 1U
The Cadco Systems Model 12-1000 is a passive channel hybrid combiner that consolidates twelve individual RF inputs — from channel processors and modulators — into a single coaxial output. It is a fully passive design requiring no external power, operating across a frequency range of 5 MHz to 1 GHz. A -20 dB test point is provided for signal monitoring without interrupting the combined output.

Applications
The Cadco 12-1000 is used in cable television (CATV) headend systems to combine the RF outputs of multiple channel processors and modulators onto a single coaxial distribution cable. In a typical CATV headend, each channel processor or modulator produces a distinct RF channel; a passive combiner like this aggregates all those channels so they can be distributed downstream as a single composite signal. The passive hybrid design keeps insertion loss predictable and consistent across the full 5 MHz–1 GHz band, making it suitable for both standard and broadband cable plant applications. This type of headend combining equipment was widely deployed in cable system headends from the 1990s into the 2000s and continues to see use in legacy cable infrastructure, small system operators, private cable (SMATV) installations, and hospitality/MDU distribution systems where channel processors and analog modulators remain in service.
This Cadco Systems 12-1000 12-Input Passive RF Combiner has been inspected and appears to be in good used condition. The chassis is clean with only minor surface wear typical of used rack equipment. The rear F-connector input ports and output connector all appear intact with no visible damage. The unit was pulled from a working environment where it was previously in use.
