QuickerTek iBook antenna
QuickerTek has announced "the first" for models with AirPort wireless capability, including AirPort Extreme. This new antenna is an external device that features 5.5dBi of power and improves the wireless range and signal strength in all wireless environments. "This new antenna adds 25 to 40 points to the MacStumbler rating - a popular application used for measuring wireless performance. Perhaps more impressive is that iBooks now have another 200-300 yards of wireless range effectively doubling the stock capability." It also features connections for other QuickerTek external antennas such as directional antennas. It works with all iBook models and is available for $100 (with a one-year warranty).
