The 50 Ω cable is mainly used to transmit data signals in two-way communication systems. Its application fields are relatively wide, including signal testing, computer Ethernet backbone network, wireless antenna feed cable, GPS global positioning satellite antenna feed cable and mobile phone system. The 75 Ω cable is mainly used to transmit video signals. Transmission of TV signal through cable is a typical application. At this time, F-type connectors are commonly used, such as home cable TV antenna connection. Another application is to transmit video signals between DVD player, VCR, security monitoring and other systems and equipment. At this time, it is usually referred to as audio/video (A/V) cable and connector. At this time, BNC and RCA connectors are commonly used. 75 Ω cables are usually solid center conductor cable RG59B/U and stranded center conductor cable RG59A/U. 75 Ω cable is mainly used for video signal transmission, while 50 Ω cable is mainly used for data signal transmission.
