Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feed lines connecting radio transmitters and receivers to their antennas, computer network (e.g., Ethernet) connections, digital audio (S/PD-IF), and distribution of cable television signals.
RG-7 is a low-loss, 75 Ohm coaxial cable with a double shield. This type is frequently used for broadband and cable TV applications.
