    I won a nokia car kit to use with my 6340i on eBay and need to get an
    antenna for it. I know that I need a dual band. Would a triple band hurt the
    kit, phone or reception? Is there a difference in the brand, and if so which
    should I look for and which should I stay away from?

    Thanks

    Unless you're planning on driving around America in your car with the car
    kit installed you won't need triple band. Also, a dual band aerial will work
    reasonably well with all three bands as two of the bands are pretty close in
    frequency.

    There are various types of aerial available. You should first decide if you
    want to drill a hole through your car roof. The highest gain is achieved
    with the shortest length of directly connected high quality co-axial cable
    connected to a good aerial such as a half wave whip. At most this would be
    about 17cm long, depending on the aerial design if it's dual band it might
    be 26cm at most. However, longer doesn't always mean better.

    If you don't want to drill a hole then you can use a through glass aerial.
    These have a coupler that sends the signal through the glass of your
    windscreen to a coupler on the other side, and vice versa. Of course this is
    not quite as good as a direct connection. The antenna whip on the outside
    can be the same as stated above.

    If you don't want anything on the outside of your car you can use an
    internal aerial which sticks somewhere on the inside of the car. Or even one
    of those "tax disc holder aerials". However, these are all extremely poor in
    performance compared to either of the above.

    You can get a variety of whip designs. Some try to save space by coiling the
    aerial so you can get aerials from a few cm in length the lengths stated
    above. Compressing the aerial like this does affect performance slightly.

    I should have said that I want to use a glass mount antenna.
