SMA and RP-SMA Coaxial Cable Connectors

SMA connectors are used for device internal cables as well as external antenna connectors for small antennas. Most amateur radio handheld radios do use a SMA female connector. SMA connectors can be used up to frequencies of more than 14GHz, depending on the model of the connector. The SMA connectors offered here have a gold plated center conductor and nickel plated exterior.

For Wifi equipment (wireless LAN) often so called reverse polarity, or RP-SMA 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.

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.

WiMo offers a good range of cable tools .
