| Image | Class or connector name | Used for | Notes |
|---|---|---|---|
| RF connectors (radio frequency signals). Generally use coaxial cable types such as RG-6 and RG-59 (except for twin-lead). | |||
Belling-Lee/IEC 169-2 connector |
TV aerial plug, (a.k.a. PAL connector in Europe) | Television antenna connection for most video devices outside North America. Used by early home computers and game consoles to connect them to TVs because of the lack of any other connector. | Generally not used in North America. |
| BNC (Bayonet Neill-Concelman) | Alternative to RCA for professional video electronics.
Protocols:
|
75 Ω for video signal (SDI and CoaXPress) on, for example, RG59 and RG6. 50 Ω for data link, like Ethernet on RG58. 93 Ω on RG62. |
|
50 Ω (white/bottom row) and 75 Ω C connectors (red/top row) |
C connector (Concelman connector) | ||
General Radio 874 connectors |
GR connector (General Radio connector) | ||
| F connector | Used for most North American TV antenna connections, as well as satellite and cable systems worldwide. Also common in North America for early home computers and game consoles, older VCRs, RF modulators, and even CECBs due to lack of other connectors. | Generally not used outside North America for TV antennas (except for satellite reception) | |
| N connector (Neill connector) | |||

| Twin-lead | Used for older TV antenna installations in the US and various other countries worldwide. Current use generally limited to baluns to adapt 300 Ω twin-lead to/from 75 Ω F connector. | Replaced by F connector in North America and Belling-Lee Connector in other countries outside North America. | |
| UHF connector (e.g. PL-259/SO-239) | |||
