    Wifi antenna

    Because i am planning for a new mobo, the mini-pici wifi card is replaced by a Alfa usb wifi.

    Now i have an antenna from the mini pci car, its about twice as long as the the one that came with the alfa which is 2 db.

    Looking for an antenna with a better db, i came acros this: Omni2 Car Antenne:

    specs:
    2400 - 2483 MHz
    Kabellenght 2 meter
    Gain 2 dBi
    Dimensions 1 cm x 2 cm x 15 cm
    Connector Type RP-SMA

    now its only 2 db, but would it be better for use in the car than a normal wifi antenne of about 7 db or 9db?

    I will mount it in the sunroof, next to the gps:

    Never seen an antenna like that. Mounting it in the sunroof will kill a bit of your signal. Microwaves reflect off metal. The access points you're going to be connecting to probably aren't going to be right above the car.
    Failure is not an option....



    It's installed by default on every version of Windows.
