What is the name of the TV antenna interface?

Television antenna interface is called "radio frequency interface" (also called radio frequency interface, coaxial cable interface and closed circuit interface), which belongs to analog signal interface. All TVs support this interface.

The shape of the interface is shown in the figure, commonly known as "cable TV interface". It is through this interface that the closed-circuit signal of cable TV signal line is transmitted to TV, so it is the most widely used and best supported interface.
