The Bayonet-Neill-Concelman (BNC) connector, the most common connector, is widely used in video and radio frequency (RF) applications to 2.4 GHz, 10BASE2 Ethernet networks, cable interconnections, network cards, and test equipment.
The TNC connector, a threaded version of the BNC, works up to 12 GHz. Used in cellular telephone RF/antenna applications.
The N connector is a larger, threaded connector that operates to 12 GHz. Common on 2.4-GHz antennas.
The UHF connector looks like a big center-conductor version of the N connector. Suitable up to 200–300 MHz.
The F connector is most often used in TV and antenna applications. Performs well at high frequencies.
The Subminiature A (SMA) connector is one of the most common RF/microwave connectors. Works to 12.4 GHz, and possibly 18 or 24 GHz. Used in avionics, radar, and microwave communications.
The Subminiature C (SMC) connector is a small, screw-on version of the SMA. Used to 10 GHz, primarily in microwave environments.
The Subminiature B (SMB) connector is a small version of SMC. Has a snap-on coupling. Rated from 2–4 GHz but can possibly work up to 10 GHz.
The Micro Coax (MCX) connector is similar to the SMB, but is 30% smaller. Used in broadband applications to 6 GHz.
