RG11 coaxial cable is thicker than other types of RG cable which allows it to carry signals over longer distances with less signal loss. The robust construction of RG11 coaxial cable means it can withstand exposure to the elements better than thinner RG6 cables making it suitable for use in outdoor applications. RG11 cable is used for long-distance signal transmission where long cable runs are required and high signal quality is crucial such as satellite television installations and telecommunications.
