A coaxial plug is a type of radio frequency (RF) connection that is often used with coax cables. Though commonly associated with a standard RF connector used in analogue television and radio arrays, there are actually several different kinds of coaxial connectors suited to a variety of specialist RF applications.
Types of coaxial plugs:
- BNC is a miniature RF connector with a bayonet locking system, and is commonly used in television, radio and test instruments.
- TNC is a threaded version of the BNC connector.
- UHF is a threaded RF connector that has applications in amateur radio arrays and VHF radio.
- F is an RF Connector commonly used to connect satellite television and cable modems.
- N is a threaded RF Connector that is known for its weather proof properties.
- SMA/SMB/SMC are sub miniature RF connectors. Versions A, B and C are all feature 50 Ohm impedance, and differ by their threaded, snap on, and hex nut coupling, respectively.
- MCX is a micro coaxial connector that is a smaller version of the SMB connector, often used in Wi-Fi antennas.
