What you need to connect an external Antenna Cable to a Wireless Card Most antennas come with a connector. For standardization, most people select an "N" connector so that the antenna is usable or loadable to many people who can also make use of an "N" connector. Because an "N" connector is large, an adapter is needed to connect the antenna to the wireless card. Because wireless cards have
MC-Card, MMCX, RP-MMCX, SMA Male, SMA Male RP, IPEX or other types of tiny connectors, you will select a pigtail that has an "N" connector on one end, and the corresponding connector on the other to connect to the wireless card. Of course, some people don't get antennas with "N" connectors (small whip antennas commonly use RP-TNC or Reverse SMA), so there are many kinds of varieties of pigtails.
