    I could be wronbg but

    Isotropic = An Antenna Myth.

    Umm, I thought that it was impossible to get a true isotropic as all antennas radiate in one direction or another.

    Clearly, you didn't get the joke.

    Okay, yea, I get it now. Collinears are fun to build. I've built three of them so far.
    Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69

    so what anteanas do you people have and how well do they work?
    i like using the "2.4 GHz 8 dBi Omnidirectional Antenna - RP SMA Plug Connector" from hyperlinktech dot com. beware, the 16" length is a lie. not counting the required space used for the wire, the antenna is 16.5" and screwed up a pen project i was working on.

    (RP-SMA-Male (RP male = no penis) to connect to the RP-SMA-Female connector of the Alfa adapter (RP-Female = a penis))

    is it 80 dollars worth of gain? no.

    I have had good luck with Hyperlink's stuff. The mobile mount 8.5 dBi antenna had a bad tendency of flying off my car/truck causing paint damage, and antenna damage. It was a great antenna though. I dragged it for a few miles. Not sure why you had problems with a yagi. I have one of their 14.5 dBi yagi's and have had good results. Unfortunately it is not with your exact card, but the results were great on all of my other cards as well.

    Ive had a few kinds of antennas. I use a alfa wifi card myself currently. My favorite is going to have to be my panal I like it for traveling, it will be the one I bring with me to defcon. I don’t like my yagi as much for traveling, I always wonder what airport security thinks when they see a yagi wifi antenna in a suitcase.
