Overview
Antronix is a supplier to major cable operators, and the CMC2003H-A is a residential three-way coaxial splitter aimed at the same scenario professionals encounter in the field. Three-way coax splitters introduce more insertion loss than two-way units, which can matter in weak signal areas, but this unit's 4.5 rating suggests it handles that challenge well for most buyers.
At $7.95 it is a low-cost component that fits into almost any budget. The 247-review sample is not enormous, but a 4.5 average from a category where buyers notice signal loss immediately gives the rating good credibility.
This is purely a coaxial splitter for antenna or cable TV distribution. It has no HDMI capability and does not boost signal. If your local antenna signal is already weak, a three-way split may reduce picture quality on one or more TVs. In strong signal areas, the UHDS-102A-level loss of a three-way passive split is typically not noticeable.
Pros
- Antronix is a trusted name in professional cable distribution
- 4.5 stars from 247 real-world reviews
- Very affordable at $7.95
- Compact and easy to install on any coaxial run
- Good choice for splitting antenna signal to three TVs
Cons
- Three-way split causes more insertion loss than a two-way unit
- Not suitable for weak antenna signal areas without a signal amplifier
- No HDMI capability, coaxial only
- No signal amplification included
Performance notes
Coaxial connectivity, three-output passive splitter. No resolution or gain spec is listed in the available data. Three-way passive splitters typically introduce around 5.5 to 8.5 dB of insertion loss. In strong signal markets this is not a concern, but marginal OTA antenna setups may need an amplifier upstream.
What buyers say
247 ratings at 4.5 stars is solid for a passive coaxial splitter. Buyers in this category tend to leave negative reviews quickly when signal degrades, so a 4.5 average suggests the unit performs well in typical residential signal conditions.

Frequently asked questions
Will this reduce my antenna signal quality?
Any passive three-way splitter reduces signal strength on each output port. In areas with a strong over-the-air signal this loss is generally not noticeable, but if your signal is already marginal you may see pixelation or dropouts on one or more TVs. Adding a powered antenna amplifier upstream can offset the loss.
Can I use this for cable TV as well as antenna?
Yes, a coaxial splitter works with both over-the-air antenna signals and cable TV coaxial feeds. Make sure to check your cable provider's requirements, as some setups may need a specific splitter type for MoCA or DOCSIS compatibility.
