How I Evaluate Best Coax Cables
When I test connectivity components like coax cables, I don’t just look for continuity; I dive deep into signal attenuation, RFI rejection, and physical durability—the factors that truly determine long-term performance. I focus heavily on the quality of the conductor (is it copper or simply copper-clad steel?) and the impedance rating (must be 75 Ohm for standard applications) because these fundamentally dictate signal quality. A great cable should offer efficiency, minimal loss over distance, and consistent data delivery, regardless of whether it’s powering a 4K TV or a high-speed modem.
I spend significant time analyzing the connection points because that is the most common failure location. I look for robust compression connectors or quality plating (like gold or nickel-plated brass) that resist corrosion and ensure a tight, stable fit. Price per performance is also a factor; I am always looking for the sweet spot where you get exceptional shielding—like quad shielding—without paying a premium that isn’t justified by the use case.
Choosing the Right Type for You
Selecting the right coax cable really boils down to balancing your application needs with the environment in which the cable will be placed. If you are dealing with high-frequency signals, such as DOCSIS 3.1 internet (which requires stable 3.0 GHz support) or modern satellite systems, you absolutely need an RG6 cable featuring quad shielding to minimize data loss. If the cable is going outdoors or into a wet environment, prioritizing models with robust, weatherproof compression connectors and rubber O-rings (like the G-PLUG or Nixsto) is critical to prevent moisture intrusion.
For users focused on aesthetics and safety, a CL2 or CM-rated cable, like the Adoreen or GE options, is non-negotiable for in-wall routing. Generally, I recommend paying slightly more for quad-shielded RG6 over dual-shielded RG6 if the run is over 25 feet or if you know the cable will be near high-power electronics. For short patch cables (under 6 feet), focus less on shielding layers and more on physical convenience, like the right-angle adapters offered by Adoreen or Elecan, to ease installation in tight quarters.

Common Questions About Best Coax Cables
What Are the BEST COAX CABLES I Should Buy for 4K TV and Gigabit Internet?
For high-bandwidth applications like 4K streaming and gigabit internet (which often run up to 3 GHz), I highly recommend choosing an RG6 cable that explicitly features quad shielding. This level of protection ensures minimal signal attenuation and superior rejection of RFI and EMI, which is critical for maintaining high speeds and avoiding video freezing. Look for cables that specify support for 3.0 GHz or higher, like the Adoreen or Cable Matters quad-shielded models I tested.
Is There a Difference Between RG59 and RG6 Coaxial Cable?
Absolutely, yes. RG6 cables contain a larger conductor and thicker insulation, which results in much lower signal attenuation, especially at higher frequencies (above 50 MHz). In my experience, RG59 is really only suitable for older, low-bandwidth CCTV or analog video signals over short distances. For modern cable TV, high-speed internet, and satellite, I always advise upgrading to RG6 for superior performance and signal integrity.
What is the Importance of 75 Ohm Impedance in Coax Cables?
The 75 Ohm impedance standard is crucial because it matches the typical impedance of residential broadcast distribution systems, including cable TV, modems, and antennas. Using a cable with the wrong impedance (like 50 Ohm, common in radio communications) creates impedance mismatches that cause signal reflections (return loss), severely degrading signal quality and speed. Sticking to 75 Ohm is non-negotiable for consumer A/V applications.
Do Gold-Plated Connectors Actually Improve Coax Cable Performance?
While gold itself doesn’t improve signal transmission quality over copper, its crucial benefit is corrosion resistance. Unlike nickel or silver plating, gold resists oxidation and tarnish, which prevents increased resistance at the connection point over time. In humid or outdoor environments, I find that gold-plated connectors significantly extend the reliable lifespan and maintain consistent signal quality far longer than standard metals.
How Can I Measure and Reduce Signal Attenuation in My Coax Setup?
Signal attenuation is the loss of signal strength over distance. You can measure it using a signal meter on your modem or TV box diagnostics. To reduce it, first ensure you are using the correct RG6 cable type and use the shortest run possible. Secondly, utilize high-quality connectors (like compression fittings) and minimize the use of cheap, unrated splitters, which are major sources of signal loss.
