Frequently Asked Questions About best internet coax cable

What is the difference between RG59 and RG6 coaxial cable?

RG6 is the modern standard for high-bandwidth applications like cable internet, digital TV, and satellite. It has a larger conductor and thicker insulation compared to the older RG59, resulting in much better signal quality and less signal attenuation at higher frequencies. For high-speed broadband, an RG6 cable is mandatory to ensure peak performance.

Does the length of my coax cable affect my internet speed?

Yes, absolutely. Longer cables lead to more signal attenuation (loss). While a high-quality, heavily shielded cable (like the G-PLUG or TechDirect models) minimizes this effect, you should always use the shortest practical length of the best internet coax cable possible. Keeping runs under 50 feet is ideal for maintaining optimal modem signal strength.

Are gold-plated connectors worth the extra cost?

Gold plating on F-connectors helps prevent corrosion and oxidation over time. While the gold itself doesn’t significantly speed up the signal, preventing corrosion ensures the connection remains physically clean and stable years down the line, especially useful in humid environments or outdoor installations.

What is a compression connector and why is it important for signal quality?

Compression connectors (featured heavily on G-PLUG products) are mechanically superior to traditional crimp or twist-on connectors. They create a 360-degree watertight seal around the cable jacket. This airtight and secure connection prevents moisture ingress and eliminates micro-gaps that could allow radio frequency interference (RFI) to leak into the signal path, crucial for maintaining your best internet coax cable connection integrity.

Should I replace the coax cable provided by my ISP?

In almost every case, yes. Internet Service Providers (ISPs) often use thin, cheaply made RG6 cables with poor shielding and weak, twist-on connectors to save costs. Upgrading to a professional-grade coaxial cable, such as those reviewed here with multi-layer shielding and robust connectors, is one of the easiest ways to improve modem signal levels, reduce errors, and ensure you are getting the full speed you pay for.

Can I use the same coaxial cable for both internet and TV?

Yes, RG6 coaxial cables are designed to handle the frequency requirements for both high-speed internet (broadband) and digital/satellite TV signals simultaneously. As long as the cable is rated at 75 Ohms, it is compatible with standard modems, cable boxes, and digital antennas.
