    Can anyone explain the difference between a Penta-Band antenna and a Quad-Band antenna?

    Guessing here, but I know some stuff about radio so...

    An antenna has to be a particular size so that it resonates at the desired frequency. The size is related to the wavelength of the radio signal it's designed for.
    Higher frequency = shorter wavelength = smaller antenna.

    A quad band one will work at four different frequencies.
    So presumably a penta band one will work at five.

    So is one particularly better than the other?

    Good guess. Is penta-band better? Depends on whether you'll be travelling to asian countries where the 5th band, 800 mhz, is used. One phone I read about (a nokia) actually had a wcdma band as well. Now that would be cool.
