Most laptops' internal WiFi do not support an external antenna. So if you are getting a weak WiFi connection, how do you boost the signal by connecting to an external high performance antenna?
The miniPCI card is the WiFi card of the size about 5cm x 3cm located inside the laptop. You could easily find it by turning your laptop bottom up, removing two screws followed by opening the lid. The miniPCI card is connected to two internal antennas labelled as "MAIN" and "AUX". Simply replace the "MAIN" by the U.FL RF connector of the 4 inches U.FL to RP-SMA-female pigtail, which allows you to in an external high performance antenna such as the +12dBi TurboTenna.
What's more? You could use this cable for wireless routers. Simply open the casing and you'll find the U.FL leads on the PCB (Printed Circuit Board). Replace them to bypass the non-detachable factory antennas.
As you can see, the bulk head of the RP-SMA-female allows you to fix the connector on a panel permanently where it holds the antenna.
The U.FL we use is a silver plated ultra low-loss high performance thin RF cable. it is fitted with the CNC milled RP-SMA-female to ensure negligible insertion loss. Together they differentiate with good value for money.
This auction offers a brand new, fully tested, very high quality, radio Pigtail made of dia. 1.13mm Cable.
It features to U.FL to RP-SMA(female) Bulkhead (Hirose/iPex/Mini-PCI Compatible) RF Connector.
