Common Questions About best outdoor coax cable

What is the difference between RG6, RG59, and RG11 coaxial cable?

RG6 is the modern standard for residential digital video, satellite, and high-speed internet applications because it handles higher frequencies (up to 3 GHz) and offers lower signal loss than the older RG59. RG59 is generally only used for low-frequency CCTV applications. RG11 is much thicker and typically reserved for extremely long runs (over 150 feet) where maximum signal preservation is required, but it is much more expensive and harder to bend than RG6.

Does UV light damage outdoor coax cable?

Yes, direct exposure to ultraviolet (UV) light causes the outer PVC jacket of the coax cable to become brittle, crack, and eventually fail, allowing moisture to reach the inner conductors and shield. When selecting the best outdoor coax cable, ensure the description explicitly mentions UV resistance or a UV-stabilized jacket to ensure longevity.

How important is the shielding (Dual, Triple, Quad) for outdoor use?

Shielding refers to the layers of foil and braided mesh surrounding the center conductor. For outdoor installations, especially in urban areas or near power lines, shielding is highly important. Quad shielding (four layers) provides the best defense against radio frequency interference (RFI) and electromagnetic interference (EMI). Triple shielding is sufficient for most residential applications, while dual shielding may be adequate for very short runs in quiet areas.

Can I bury an outdoor coax cable directly in the ground?

Only if the cable is specifically rated for direct burial. Most standard outdoor cables are weatherproof but not designed to withstand constant moisture, soil abrasion, and temperature fluctuations underground. For burial, look for cables with a flooded jacket or a specifically designated direct burial rating to prevent water from wicking into the cable ends.

What causes signal loss over a coax line?

Signal loss (attenuation) increases with cable length and frequency. The longer the run, the weaker the signal. Additionally, damage to the cable jacket, moisture intrusion into the connectors, or using poorly rated splitters can dramatically increase signal loss. That’s why high-quality, weatherproof connectors and durable jackets are critical for the best outdoor coax cable performance.

Should I use compression connectors or screw-on connectors outside?

You should always use compression connectors (like those found on the G-PLUG and THE CIMPLE CO cables) for outdoor applications. Screw-on connectors offer minimal moisture protection and can easily come loose. Compression connectors create a 360-degree seal around the jacket, providing superior mechanical connection strength and exceptional resistance against water and corrosion.
