Overview
A coaxial signal adapter from Antronix, model CMC2003H-A-MoCa, finished in black. The MoCA designation in its model name points to coax based signal or networking use, though the listing itself lists only coaxial connectivity.
Antronix builds this under the Video Converters category, but the MoCA name in its own model number is normally associated with passing a network or video signal over existing coaxial wiring rather than converting one video format to another. With just coaxial connectivity listed and no Ethernet or HDMI spec included here, the exact ports and use case are best confirmed against Antronix's own documentation before buying.
- Coaxial connectivity
- MoCA reference in model name
- Black finish
- 4.4 stars, 281 ratings
Who it's for
Fits a buyer working with existing coax wiring in a wall who needs an Antronix branded adapter compatible with MoCA signaling. Not a fit for anyone expecting HDMI or component video conversion, since no such connectivity is listed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Coaxial connectivity for existing wiring
- 4.4 star average across 281 ratings
- Only one connectivity type listed, coaxial
- No description or further spec detail provided
Performance notes
MoCA technology, referenced in the model name, works by carrying a signal over the same coaxial cable already run through a wall for cable TV, avoiding new wiring. The listing itself confirms only a coaxial connection point, so the other side of that connection, whether Ethernet, another coax run, or something else, is not specified here and should be checked directly with Antronix.
