The RG-11 is constructed for applications in which low signal loss is of premier importance, and it is actually the thickest of the coaxial cable family. It can operate on frequencies as high as 3 gigahertz (GHz). Thus the RG-11 is perfect for cable runs that require a lot more length and is often used for connections between antennas and HDTV over-the-air receivers. Also, since it can be run for as long as 400 feet without major signal loss
