    I'm student of Yeung Nam university, Korea.
    First, Sorry I'm poor at english.

    Yesterday, I did scan wifi signal, 1M, 2M,..10M from AP.

    I have to compare two values, actually scan value and fries formula value.

    but I don't know about gain value of MacBook air wireless antenna.

    How can I find it?

    In Apple technical page, not exist.

    The Mac Air's antenna gain is not going to be published by Apple, that is surely an internal specification. At best, you might find some research paper where it has been calculated, but that is such a niche interest you're not likely to find such information anywhere.

    Have you tried looking on the website of the antenna manufacturer?

    There is nothing you can do about it. There are no third-party high gain antenna you can buy for the Macbook, why worry about it?

    It's probably not spec'd anywhere, but I would assume the antenna is a typical board trace antenna with a nominal gain of 3db of a half-wave dipole.

    Who says he's worried about it?

    Sounds like he's trying to research something.
