Collection: RF Coaxial Connectors

An RF coaxial connector is a precision electrical connector designed to terminate a coaxial cable while maintaining its characteristic impedance — typically 50 Ω or 75 Ω — across a defined frequency range. They are used in antenna systems, test equipment, broadcast infrastructure, and consumer electronics. Browse our full range in Connectors & Terminals.

50 Ω connectors are the standard for RF communications, amateur radio, test equipment, and many wireless systems. 75 Ω connectors are used in video, broadcast, satellite, and cable TV distributions. Mixing impedances causes reflections and signal loss, so always match your connector and cable impedance. See our F-Type, BNC & Coaxial Connectors for 75 Ω options.

Satellite TV installations in Europe almost universally use F-type connectors on 75 Ω coaxial cable. F connectors are low-cost, easy to install, and perform well up to the frequencies used by satellite LNBs. For a selection of F-type connectors, visit our F-Type, BNC & Coaxial Connectors page, and for matching cables see Power & Mains Cables.

Yes — SMA connectors are very common in Wi-Fi and other 2.4 GHz / 5 GHz applications, particularly for attaching external antennas to routers, access points, or USB Wi-Fi adapters. Note that reverse-polarity SMA (RP-SMA) is used on many consumer Wi-Fi devices, so verify which standard your device uses before ordering. Browse our Connectors & Terminals range for options.

The tools required depend on the connector type. Compression F connectors need a compression tool and a coax cable stripper. Crimp-style connectors require a matching crimp tool and die. Solder-type connectors need a soldering iron and appropriate solder. Some basic connectors can be fitted with a sharp knife and pliers, but purpose-made tools give more reliable results. Explore our Power & Cables accessories section for related items.

A well-matched, correctly installed RF connector contributes minimal insertion loss and maintains impedance continuity. Poor connectors or improper installation introduce reflections (measured as return loss or VSWR), signal loss, and can even admit moisture that degrades performance over time.
