    This is the connector you need if you want to breakout your wifi antenna from the inside of your laptop (I.E. wardriving)

      lovely idea, except for the horribly designed by HP. anyone know where i can find a 12" version?

    Do you buy chance have this any longer?
    I have a 17 Laptop, which they have the Wifi Card in the middle of the board, and to successfully reach the side of the case with an empty spot to drill a hole for the SMA connector, I would have to snack the wire.
    I bought the 4in one, without making note of the length. I need something longer, 9" or more.

    Does anybody know what is the longest size of this type of wire that I can find and where I can find it?

  • Can this cable be used with the Arduino Yun?

  • Member #74195 / about 12 years ago / 1

    Anybody have tips on how to crimp on a new U.FL connector? I actually need to make this cable shorter so I want to cut, strip, and connect a new U.FL female connector on.

    This connector seems to be somewhat fragile - the U.FL end will separate from the cable is you aren't careful - I've had it happen to 2 of mine.
    Relatedly, any idea when they will be back in stock?

    • Volkemon / about 14 years ago / 1

      Ditto's on the fragile end. 2 of 3, and I was being VERY careful after number 1!
      I took my one remaining and put shrink tubing that barely fit over the connector. Pushed as far out on the connector as possible,then shrunk. It helps a lot.
      I do note the other end has heat shrink tubing from manufacture. Maybe this step could be added to the small end. If soldering the cable to the XBee directly fails, I will mod the new cables this way.

        The U.FL connector is only intended to be disconnected 3 or 4 times. Keeping spares around is a good idea.

      It's looking like it will be late August before we'll see these back on the storefront.

Excellent quality!

I use these with high power 900MHz XBee modules in rockets and high altitude balloons. these things are tough and the ufl connection is very sturdy.
