RG11 cable is a type of coaxial cable that is commonly used for high-speed Internet connections, particularly in long-distance installations. The maximum distance over which RG11 cable can reliably transmit Internet signals depends on several factors, including the quality of the cable, the signal frequency, and the networking standards being used.

In general, RG11 cable can transmit Internet signals over distances of up to several hundred feet without significant signal loss. However, for longer distances, signal amplification or signal repeaters may be required to maintain signal strength and quality.

For specific installations, it’s best to consult with a professional installer or refer to the manufacturer’s specifications to determine the maximum distance for reliable Internet transmission using RG11 cable.
