TNC connectors are used mainly with commercial radio products. They are suitable for frequencies up to several GHz. In contrast to SMA or BNC these connectors are more robust and better suitable for heavy cables or antennas. Furthermore TNC connectors are better suited for outdoor use than SMA or BNC.
For Wifi equipment (wireless LAN) often so called reverse polarity, or RP-TNC connectors are used. That means that the center conductor has an inversed polarity. Instead of a male conductor you find a female contact and vice versa. This leads to quite some confusion about what is a plug and what is a jack... Usually all connectors with an outside thread are called a jack, all with a nut with inner thread are plugs, regardless of the polarity of the center conductor. On our website Wifi connectors this is explained in greater detail and with pictures.
Most of the connectors offered here are crimp connectors. That means that these connectors are not soldered but that the outer shield is pressed onto the shaft of the connector with a special tool. The center conductor is usally soldered. Of course we supply the required tools as well, please see Crimp tools.
If you want to crimp the connectors yourselves you will need also the information on the precise lengths to which a cable (outer isolation, shield and inner isolation) must be stripped. This information is to be found in the following document:Cable sizes for crimp connectors (PDF, 260KB)
We also offer custom made coaxial cables, please see here.
