Comparison Short Insights: Choosing Your Cable

When selecting the best type of coax cable for internet, focus on length, shielding, and the connector type.

For short desktop runs (under 10 feet), the difference between double and quad shielding is minimal, but the quality of the connector matters immensely. The G-PLUG and Nixsto options excel here by providing superior gold-plated or compression connectors, which resist noise where the cable terminates.

The SUPERBAT RG179 stands alone as the best choice if you need maximum flexibility in a tight cabinet, but remember its thin profile means it should never be used for runs over 5 or 6 feet.

For medium runs (10 to 25 feet), balancing cost and protection is key. The energeaster 10FT with Triple-Layer Shielding is an excellent intermediary choice if you live in an area with potential interference, offering more protection than standard RG6 without the stiffness of quad shielding.

If your run is over 30 feet or goes outdoors, the G-PLUG Quad Shielded 50FT is the definitive choice. Quad shielding drastically minimizes signal attenuation over distance, ensuring your internet modem receives the strongest possible signal, which directly correlates to stable speed.

Frequently Asked Questions About best type of coax cable for internet

Why is RG6 considered the best type of coax cable for internet?

RG6 cable has a thicker conductor (usually 18 AWG) and better dielectric insulation compared to older standards like RG59. Critically, RG6 is designed with better shielding to handle the higher frequencies (up to 3 GHz) used by modern cable internet (broadband) and satellite systems. This results in less signal loss (attenuation) and better immunity to outside electronic interference.

How does shielding (Double vs. Quad) affect my internet speed?

Shielding doesn’t increase your maximum potential speed, but it protects your connection from interference that causes instability and slowdowns. Double shielding is usually fine for short, indoor runs. However, if the cable runs parallel to power lines, is outdoors, or exceeds 25 feet, upgrading to triple- or quad-shielded RG6 is crucial. Quad shielding provides the maximum barrier against RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference), ensuring a cleaner signal reaches your modem.

Should I choose a cable with gold-plated connectors?

While gold-plated connectors are a popular feature, they don’t significantly improve signal quality over high-quality nickel or silver plating. Their primary benefit is corrosion resistance. If you live in a humid climate or are using the cable outdoors, gold plating ensures the connection points won’t degrade over time due to oxidation, helping maintain long-term signal stability.

What is the ideal length for a coax cable connection?

Shorter is always better when dealing with high-frequency digital signals. Each foot of cable contributes to signal attenuation (loss). You should aim for the shortest practical length required to run neatly between your wall plate and your modem or device. Using a 50-foot cable when a 10-foot cable would suffice will unnecessarily degrade your signal strength.

Does the cable’s impedance matter for broadband internet?

Yes. Broadband internet and cable TV systems are engineered to operate optimally at 75 Ohm impedance. It is essential that you use only 75 Ohm cables (like RG6 and RG59) and 75 Ohm F-type connectors and splitters. Using a 50 Ohm cable (common for radio equipment) will cause significant signal reflections and potentially severe connection issues.

Are compression connectors better than crimped connectors?

Absolutely. Compression connectors (like those used on the G-PLUG cables) use a 360-degree seal that is mechanically stronger and provides superior protection against moisture and noise ingress than traditional crimped connectors. This solid connection at the terminal is critical for maintaining the signal integrity required for high-speed internet.
