Recessed F-coaxial connectors position the hex nut farther into the insert, which helps prevent the jack from rotating during installation and use; many recessed options are also self-terminating. Non-recessed connectors use a standard, more exposed mounting design while still fitting keystone wall plates for cable TV and other coaxial connections.

F-coaxial connectors for wall plates are designed to fit keystone-style wall plates, including compatible decorator faceplates and structured wiring plates. Many also mount in compatible low-voltage installation brackets or mud rings, but verify that the mounting system accepts keystone inserts before installation.

For cable, satellite, and other high-frequency applications, compare the connector’s stated bandwidth with the system requirements, noting that some inserts in this category specify up to 3 GHz. Also review features such as female-to-female F-type construction, gold plating, a recessed hex nut that helps limit jack rotation, and self-terminating design.

Choose a straight F-coaxial connector when both sides of the wall plate connection use F-type coaxial cables, such as connections for cable TV, satellite, cable modems, or other coaxial equipment. Choose an F-coaxial-to-RCA adapter when you need to connect an RCA cable or device on the front of the wall plate to an F-type coaxial cable behind it for audio or video distribution.
