improving airport range

[regre7]

I have a MBP, and I'm always irritated that my friend's MB can get better wireless range than me. I'd like to know about any methods that I could use to improve my wireless range, anything from settings to external antennas.

I bought an external antennae for my Mac mini from http://www.quickertek.com/. They have a big range of products to choose from.
