To improve my signal at home, as an alternative to adding an external antenna to my Airport Extreme base station (which does not have the antenna port), is there an improved antenna I can plug into my G5 antenna port to replace the small one that came with the G5?
Dual Processor G5,
Mac OS X (10.4.3),
Power Book G4
One of the simplest ways to get better reception is to move the T antenna from the back of your G5 to someplace higher and away from all the metal of the G5.
You can do this with a simple extension cable such as:
You can also use the same extension cable with a different antenna if you need for signal strength, but before buying an additional antenna, I'd try the cable and the small T antenna first.
