USB adapters with chip antenna

    I have been using some small reasonably cheap USB 802.11b/g adaptors
    obtained from a local electronics store under their own branding (Dick Smith
    Electronics for Aus and NZ) but these are now non-stock.

    We remove the flip up chip antenna and wire directly to a biquad with
    minimal lead length. Performance on the end of a USB cable is excellent.

    Are there any suggested or recommended small USB units with similar antenna
    that can be readily removed and the unit fitted to the rear of the biquad as
    in the past? They need to have driver availability for Win98 thru to Win XP.

    I don't have a photo, but I unsoldered the PIFA antenna, attached an
    SMA connector in its place, and connected it to an external patch
    antenna. It's current running on a neighbors rooftop.

    I have found that generally a B/G version appears to be a bit more sensitive
    than a straight B version alone by a couple of dB hence looking for G
    versions even though they are operating a B units, The distances being
    covered around out local neighbourhood mean that we must optimise for best
    signal and that extra couple of dB just improves our margins.

  4. Maybe Jeff can comment on this observation.
    The Network Everywhere NWU11B seems to be very similar to the Linksys
    WUSB11 with a diffirent color case.
    They can sometimes be found on clear outs very inexpensively.
    This model can be tricky to set up non XP if you allow the computer to
    reboot after the software install ( before inserting USB connection).
    Funny part is that Windows itself often tells you to reboot before
    attaching the USB connection.
    After reading the manual you discover the working procedure is to
    attach the cable after software install with no reboot.
    Hence the clearouts.

    The FCCID tells the tale. They do seem to have different FCCIDs, but
    looking at the photos on the FCC web site might show that they are the same
    under the plastic.

    Linksys WUSB11 2.6: FCC ID PKW-WUSB11
    Network Everywhere NWU11B FCC id 07J-GL2411USB

    I didn't see these on the units themselves, but they are listed as such in
    some Linux WiFi forums.

    Sorry, no clue. I'm too lazy to compare internal photos on the FCCID
    web pile. However, even if they were identical, various vendors have
    been known to enhance and extend software based features. For
    example, the common GL2422 hardware is almost identical for all the
    following units:
    http://www.vallstedt-networks.de/?vendors/GST_Vendors
    but the firmware is anything but identical.
    PKW is Cisco-Linksys in Irvine.
    That's O7J not Zero 7J as in Global Sun Tech in Taiwan.
    Where did you find the list? I've been looking for a hardware list
    with FCCID numbers so I wouldn't have to beg for details when
    answering questions. The FCCID search tool is rather clumsy and often
    fails to find things that I know are there.

    Which doesn't mean much... Sometimes you'll find that a "brand name"
    device has an FCC-ID directly from the true manufacturer. Netgear always
    has their own, even if the widget appears identical to something else.
    (Jeff knows this, just tossing some light out for others.)
    Google Linksys WUSB11 FCC-ID

    For the Orinoco, the reverse is immediately amusing, since most of the
    myriad re-branders of that once-excellent card didn't get their own FCC-ID.
    It seems that I can't get to the query screen directly. If I get
    there via one other screen, it works, if I get there via another link that
    I have stored, it doesn't work. There is some caching going on, so once it
    works, either path works. Sometimes the pdf files aren't available, as the
    OP noted. Sometimes it works.
