Coaxial cable connectors attach devices to computers or a host device using coaxial cables. They consist of a central conducting wire covered by an insulating shield, and encased in a final cylindrical layer. They are capable of high-speed transfers and commonly used in cable modems, video and broadcast equipment, and some older computer networks.
Types of Coaxial Cable Connectors
Kinds of Coaxial Cable Connectors include the following:
SMA connectors have an impedance of 50 ohms and operate in frequencies up to 18 GHz. They are commonly used in broadcast antennas, and reverse-polarity versions are widely used in WiFi devices.
BNC connectors come in male and female plugs. Male connectors have rotating rings that lock onto the ends of female connectors. They are used in professional digital and analog video, radio connections, and some Ethernet networks.
TNC connectors are available in 50-ohm and 75-ohm impedance ratings and operate in the 0 to 11 GHz band. Standard connectors are used in radio and wired applications, while reverse-polarity versions are also used in WiFi applications.
Choosing Coaxial Cable Connectors (Buying tips)
Attachment: Choose a coaxial connector that crimps onto the cable instead of the screw-on type. Crimp connectors are more stable and protect both the conductor wires and the internal wiring on the cable.
Angle: Choose a right-angle connector to improve mobility in tight spaces, such as a desktop setup. This is also ideal for real-time recording, where the equipment has to be moved while connected to the computer or host device.
