Overview
['The Antronix CMC2003H-A-MoCa is a 3-way coaxial splitter built to work with MoCA adapters. Regular coax splitters can block or degrade the higher-frequency MoCA signals that ride on the same coax alongside TV or antenna signals. A MoCA-compatible splitter is designed to pass those frequencies through, keeping your MoCA network functional after the split.', "At $7.75, this is one of the most affordable ways to get a MoCA-rated 3-way coax splitter. The 281-review base and 4.4-star average from Antronix buyers reflect the brand's track record in commercial cable plant infrastructure applied to a consumer product.", 'Standard coaxial connectivity means it uses F-type connectors and works with antenna, cable TV, and MoCA signals on the same line. For most homes adding a third TV drop or expanding a MoCA network, this is a practical, inexpensive solution.']
Pros
- MoCA-compatible design preserves high-frequency MoCA network signals that standard splitters block
- 4.4-star rating from 281 buyers shows strong, consistent real-world performance
- At $7.75, it is among the most affordable MoCA-rated 3-way coax splitters available
- Antronix is a commercial-grade cable infrastructure brand with genuine engineering pedigree
- Works with F-type coax connections standard in antenna and cable TV installations
Cons
- Passive design introduces signal loss, which compounds more with 3 outputs than with 2
- A 3-way passive coax split can drop signals enough to cause issues with weak OTA antenna reception
- No amplification means it may not suit installations with long cable runs
Performance notes
This is a passive 3-way coaxial splitter with F-type connections and MoCA compatibility. Passive 3-way splitters typically introduce around 5.5 to 7.5 dB of insertion loss per port. MoCA compatibility specifically means the splitter passes signals in the 1125 MHz to 1675 MHz frequency range used by MoCA 2.0 adapters. No additional specs such as frequency ceiling or isolation figures are listed in the product data.
What buyers say
With 281 reviews and a 4.4-star average, buyers are broadly satisfied. Antronix products in this price range tend to attract buyers who have done their research, and the consistent positive scores suggest the MoCA claim holds up in practice. The low price makes it easy to recommend without much hesitation.

Frequently asked questions
What makes this different from a regular 3-way coax splitter?
The MoCA designation means this splitter is designed to pass the high-frequency signals used by MoCA adapters, which ride above the traditional cable TV frequencies. A standard splitter may block or severely attenuate those higher MoCA frequencies, breaking your MoCA network. This unit is built to handle both signal types on the same coax line.
Will this hurt my OTA antenna signal strength?
Any passive 3-way splitter will reduce signal strength at each output, typically by 5.5 to 7.5 dB per port. If your antenna signal is strong, this loss is manageable. If you are on the edge of receiving certain channels, you may need an amplified 3-way splitter to compensate for the loss and maintain reliable reception across all three outputs.
Do I need a MoCA splitter if I only use it for TV signals?
No. If you are not using MoCA adapters to extend ethernet over your coax wiring, a standard non-MoCA splitter works fine and may cost slightly less. The MoCA rating only matters if you have MoCA adapters in the same coax system. For a pure OTA antenna or cable TV split, either type will work.
