Gourt Home::Gourt :: RF connector
An RF connector is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection. Mechanically they provide a fastening mechanism ( thread, bayonet, braces, push pull) and springs for a low ohmic electric contact while sparing the gold surface thus allowing above 1000 reconnects and reducing the insertion force.
Types of RF connectors include:
Standard types
- BNC (Bayonet Niell-Concelman)
- C connector (Concelman)
- GR connector (General Radio)
- F connector, used for U.S. domestic television installations
- IEC 169-2 connector, also called Belling Lee connector used in the UK and some other countries for domestic television installations and as FM connector for radio. It is standardised in EN 60169-2.
- Motorola connector, standard AM-FM antenna connector used for automotive radios
- Musa connector, a 75-ohm connector used in telecommunications and video
- N connector (Niell)
- TNC connector (Threaded Niell- Concelman)
- UHF connector (e.g. PL-259/SO-239)
Miniature types
- Miniature BNC connectors
- DIN 47223 connectors
Sub-miniature types
Precision types
