http://www.radiolabs.com/products/antennas/2.4gig/2.4-mobile3.php So my parents have a PC upstairs in their house, and my dog Pavlov chewed through the cable running up there. 802.11g almost reaches my Macbook Pro up there, but not quite. So I got this antennae. I figure it will boost gain just enough for it to work. If not, I have something to mount on top of my car when I need mobile access while travelling. I'll just get a USB adapter with a reverse SMA connector like the cheap card I just ordered pops. The PCI card may have better reception with its stock antennae and I won't need this thing. But he wants it fast so I played it safe. Good buy?
