Black Antronix CMC2003U 3-way MoCA splitter with F-ports

Antronix

Antronix CMC2003U 3-Way MoCA Splitter 5-1002 MHz -3.5/-7 dB

SKU CH-8SQ3-FC617

Three-way MoCA splitter covers 5 to 1002 MHz with -3.5 dB and -7 dB ports, zinc-alloy housing, 120 dB RFI shielding and 6 kV surge protection

  • ColorBlack
  • Capacitive coupling blocks AC surges and protects cores
  • Zinc alloy housing with nickel plating resists corrosion
  • 120 dB RFI shielding from fully soldered back
  • 15 psi sealed F-ports prevent water migration
  • All ports withstand multiple 6 kV ring wave surges

Universal MoCA Splitter

The Antronix CMC2003U is a three-way coaxial splitter built for 5-1002 MHz MoCA networks carrying cable TV and broadband internet. Its universal mount design suits NID enclosures with either vertical or ports-down orientation. Installers and homeowners needing reliable signal distribution across multiple outlets will find it fits standard coax infrastructure.

Surge Protection and Shielding

Every port withstands multiple 6 kV ring wave surges per IEEE C62.41 Category A3, and proprietary ferrites stay ultra-linear after repeated hits. Capacitively coupled F-ports block AC surges while preventing core re-magnetisation and saturation. The fully soldered back delivers 120 dB RFI shielding, and spurious output remains below -45 dBmV after five surges with a +55 dBmV return signal.

Corrosion-Resistant Build

A zinc alloy diecast housing with proprietary nickel alloy plating resists corrosion, especially on the diecast backplate where exposure is highest. One-inch port spacing uses flat 15 psi sealed, SCTE compliant F-ports that prevent water migration and ensure a solid ground connection. Integrated mounting tabs, a heavy-duty ground block and a UV-resistant label support long-term outdoor or enclosure service.

Questions about this item

How do I mount the CMC2003U in a NID enclosure without trapping moisture?

Use the integrated mounting tabs for either vertical or all-ports-down orientation; the flat 15 psi sealed F-ports and 1 inch port-to-port spacing prevent water migration and maintain a solid ground connection.

What maintenance does the zinc alloy housing with nickel alloy plating require over years of outdoor exposure?

The proprietary nickel alloy plating and UV resistant label are designed for long-term corrosion resistance; no routine maintenance is needed beyond checking that F-port seals remain tight.

At what return-signal level does the proprietary ferrite core risk saturation after repeated 6 kV surges?

The ferrite blend stays ultra-linear after five 6 kV ring-wave surges with a +55 dBmV return signal, keeping spurious and harmonic output below -45 dBmV.
