The choice of RG-11 as the type of coaxial cable with the longest maximum length limitation is correct because RG-11 has a lower attenuation rate compared to the other types listed. This means that RG-11 can carry signals over longer distances without significant loss in quality. It has a thicker conductor and better insulation, which contributes to its ability to maintain signal integrity over longer runs.

In practical applications, RG-11 is often used in scenarios where the cabling must extend for substantial distances, such as between external antennas and distribution points, or in residential settings from a cable provider's drop to the home. Given its characteristics, RG-11 typically supports longer runs of up to about 1000 feet, ensuring effective transmission of signals without the deterioration that would occur in thinner cables over similar distances.

Meanwhile, other cables like RG-6 and RG-59 are suitable for shorter runs and standard applications but would experience greater signal loss over longer distances, making RG-11 the better choice for situations requiring extended lengths. RG-58, primarily used for RF applications, is also not intended for long-distance transmission, further supporting the correctness of selecting RG-11.
