4. Chaowei TV Antenna Extension Coaxial Cable(15ft) with Coupler F-Type Connector.
Having just spent a week testing heavier RG6 models, picking up the Chaowei 3C-2V immediately felt different; it’s noticeably more flexible, which reminded me of trying a lightweight tinted moisturizer after a heavy foundation. My goal here was to see if that physical flexibility compromised the signal integrity compared to its thicker, more rigid competitors. The 3C-2V designation usually implies a thinner core than RG6, so I was skeptical of its long-run performance.
My Testing Experience
I used this 15-foot cable to connect a portable outdoor antenna temporarily mounted indoors, requiring it to weave around tight corners and furniture legs frequently. The flexibility of the PVC jacket was incredible, allowing for routing that the stiff RG6 cables could not manage without bulky loops. I noticed, however, that while satisfactory for basic HD signals, when I tested this cable against the Nixsto RG6 on the same 4K feed, the signal strength measured slightly lower, indicating slightly higher loss, likely due to the thinner core.
The Honest Truth
The inclusion of nickel-plated connectors, rather than gold or high-grade compression fittings, makes me wary of long-term corrosion, especially if this were to be used in a humid coastal environment. The overall signal performance is good for standard HDTV, but it’s not ideal if you are optimizing for maximum bandwidth in an area with weak signal.

Common Questions About Best Coaxial Cable for Indoor Antenna
What Is the Best Coaxial Cable for Indoor Antenna to Ensure 4K Quality?
To ensure the best 4K quality, I recommend prioritizing RG6 cables with heavy shielding (quad or triple-layer) and gold-plated connectors, such as the Nixsto RG6. The thicker conductor and superior connection minimize signal loss and maximize bandwidth integrity, which is essential for transporting high-resolution signals without jitter or compression artifacts.
Is There a Noticeable Difference Between RG59 and RG6 Coaxial Cable for Indoor Antenna Use?
Absolutely, there is a noticeable difference, especially for modern digital signals. I’ve found RG6 cables far superior because they have a larger conductor, offering less signal attenuation at higher frequencies than the older RG59 standard. For indoor antenna signal integrity, especially for HDTV and higher, I always recommend sticking exclusively to RG6.
How Does Cable Length Affect Indoor Antenna Signal Strength?
Signal attenuation increases with cable length, meaning the longer the run, the weaker the signal reaching your TV. During my testing, I observed that even a small difference in quality between two 30-foot cables can result in lost channels. If you need a long run, you must choose a low-loss cable like the RELIAGINT 30ft RG6 to compensate for the inherent length penalty.
Do I Need Specific Connectors for a Digital Indoor TV Antenna?
While most modern antennas and TVs use standard F-type connectors, the quality of the connector material matters immensely. Nickel-plated connectors are prone to corrosion over time, which introduces noise. I prefer and recommend gold-plated connectors or high-quality compression-fit F-connectors to ensure a clean, secure, and long-lasting electrical connection.
What Does 75 Ohm Impedance Mean for My Coaxial Cable?
The 75 Ohm impedance is the standard required for video signals (cable TV, antenna, and satellite). It ensures maximum power transfer from the antenna to the receiver. Using a cable with a different impedance, like 50 Ohm (often used for two-way radio), would cause significant signal reflection and loss, severely degrading the performance of your indoor antenna.
