G5 Antennas
For those of you lucky enough to have purchased new Power Mac G5 desktops, you can now purchase higher-gain external antennas that plug into the G5's adapter. Because the G5 is such an incredible metal masterpiece, signals can't get out, so Apple ships the unit with an external add-on antenna -- ditto for Bluetooth.
QuickerTek is offering two options that plug into the G5's jack. One is just a longer antenna cable -- expensive, as antenna cables are -- to move the "T" antenna that comes with the G5 to a better position. The other is an omnidirectional antenna. They run about $55 and $130.
