Best Coax Cable for Antenna: Our 7 Picks for 2025

When I first started setting up outdoor antennas for over-the-air (OTA) TV, I learned quickly that even the most powerful antenna is useless if the cable running down to the TV is cheap. I’ve personally experienced the frustration of pixelated signals and dropouts, often due to poor quality cable or connectors. If you’re searching for the best coax cable for antenna performance, you need something that minimizes signal attenuation (loss) and protects against interference. This guide focuses on tested RG6 options that will guarantee you pull in the clearest, most stable signal possible.

Common Questions About Best Coax Cable for Antenna

What is the primary difference between RG6 and RG59 cables for an antenna?

RG6 is generally the industry standard and preferred for modern antenna and high-bandwidth signals (HDTV, satellite). RG6 has a larger center conductor and thicker insulation/shielding compared to RG59, which results in lower signal attenuation (less loss) over long runs and better noise rejection at high frequencies. RG59 is usually only suitable for short, low-frequency runs.

Does the length of the coax cable affect my antenna signal quality?

Absolutely. Signal loss, known as attenuation, increases with cable length. Even the best coax cable for antenna use will lose some signal over distance. This is why it’s critical to use the shortest necessary length and opt for low-loss RG6 quad-shielded cables (like the GE model) when dealing with runs exceeding 50 feet to minimize signal degradation.

Why do manufacturers emphasize “75 Ohm” impedance?

75 Ohm is the standard impedance required for television (broadcast and video) signals, including digital TV antennas, cable, and satellite systems. Matching the 75 Ohm impedance of the cable to the antenna and the TV receiver prevents signal reflections and ensures maximum power transfer, which is crucial for maintaining a clean, high-quality picture.

Should I choose dual shielding or quad shielding for my cable?

Quad shielding offers four layers of protection (usually two layers of foil and two layers of braid) and provides the maximum defense against electromagnetic interference (EMI) and radio frequency interference (RFI). If you live in a city, near broadcast towers, or have long cable runs, quad shielding (like the GE cable) is highly recommended. Dual shielding is sufficient for shorter indoor runs in low-noise environments.

Are gold-plated connectors really necessary for coax cables?

While gold-plated connectors do not enhance the actual electronic signal transfer compared to high-quality brass or nickel, gold is highly resistant to corrosion and oxidation. Since corrosion can quickly degrade the connection and signal quality, gold plating (as seen on the Nixsto cables) is a valuable feature, especially for cables used outdoors or in humid environments.

Can I use outdoor-rated coaxial cable indoors?

Yes, you can use outdoor-rated coax cable indoors. In fact, many indoor installers prefer outdoor-rated cables because they are built with thicker jackets and superior shielding (often with weather-sealed connectors like the G-PLUG compression type). These features guarantee maximum durability and signal protection, regardless of where they are installed.
