Powerbook G5 said:The Express doesn't have a port for an antenna, though.
I meant using the uni-directional antenna with your Mac (it makes more sense this way - it's easier to point your antenna at the nearest base station, than having to go to the base station and point the antenna at your Mac, or move so that you're in line with the base station's antenna!).
I'd need to look into external antennae again, it should be easy to add one to the G5, but for other Macs it may be something of a hack..
