    There are a limited number of wireless cards that can have their output
    power reduced (tuned, as you say) but that will never ensure any form of
    protection against a determined attacker.

    While your wireless -card- may not be able to see the airport, someone who
    really wants in to your network can drive across the street, set up a
    24dbI (or greater) directional antenna on a tripod, aimed squarely at your
    AP, and they'll see your network.
