What is the maximum length for RG11 coax cable before significant degradation of signal?

The maximum length for RG11 coax cable before significant signal degradation typically ranges up to 500 feet (about 152 meters) for standard applications. Beyond this distance, attenuation increases, leading to a noticeable loss in signal quality. For optimal performance, it's often recommended to keep the length under 300 feet (about 91 meters) when possible, especially for high-frequency signals. Additionally, the specific application and frequency can also influence the effective distance.
