I've been thinking about adding an antenna to my Airport Extreme base station, mainly so I'll have a stronger signal outside the house (well, for summer anyway). We're in a semi-rural area so I'm not too concerned with freeloaders attempting to jack my signal. I've only found two omni-directional antennas - one sold by Dr. Bott, and another made by Hawking Technologies. The Dr. Bott antenna is basically $100 (US), while the Hawking Tech antenna is under $40. Obviously the price difference is rather substantial; so I'm wondering if there's a good reason why. Do any of you have experience with either antenna? I'm especially curious to know whether the Hawking Tech antenna is a piece of crap or not. Thanks!
