QuickerTek has upgraded their external antennas designed to improve both reception and transmission of wireless signals on the on Airport Extreme 802.11n base station and the Time Capsule, now offering 5dBi tri-band antennas compared to the previous 3dBi. The company says the antennas can improve range and signal strength up to three times over the built-in antennas. The company offers three upgrade paths, from do-it-yourself kits to a mail-in service to upgrade existing units to selling units pre-upgraded with the antennas.
