Why each option
F-type connectors are the standard screw-on or push-on connectors used with coaxial cables in cable TV, satellite, and broadband installations.
The F connector (F-type) is specifically designed for coaxial cable and features a threaded or push-on coupling that connects to the coaxial cable's center conductor and outer shield. It is universally used in RF applications including cable television, satellite, and DOCSIS cable modems. ST, RJ-11, and RJ-45 are connectors for fiber optic, telephone twisted-pair, and Ethernet twisted-pair cables respectively, none of which are coaxial.
The ST (Straight Tip) connector is used with fiber optic cables, not coaxial cables, and uses a bayonet-style twist-lock mechanism.
The RJ-11 connector is used with standard telephone twisted-pair wiring and has 6 positions (typically 2-4 used), unrelated to coaxial cable.
The RJ-45 connector is used with Ethernet twisted-pair network cables (Cat5e, Cat6, etc.) and has 8 positions, not coaxial.
