An F connector is a type of coaxial connector used primarily for connecting coaxial cables to devices in audiovisual and telecommunications systems. It is commonly used in cable television (CATV), satellite television, and other video distribution systems. F connectors are prevalent in residential and commercial settings due to their ease of use and strong signal transmission capabilities. They are also widely used for networking applications, such as connecting broadband cable modems or routers to the cable service provider's network.
