RadioShack has a nice wireless version. I had one for a few days and it seemed to work when there was a signal for it. Better for laptop card and cell access both. Prices are all over the board, even amongst RadioShacks so check around.
We got out cellular antenna from WPS also. We gor cords with it to connect to our blueberries and the AT&T card.
WPS support folks are very helpful.
The antenna does seem to help when we are away from strong signals... but there have been a couple of times in town when the antenna seemed to get less of a signal than the card alone. I can't explain that.
We have the cord from the antenna routed to under the passenger seat. We can then use it on the airdcard with the laptop on the ram mount or when seated on the gaucho.
...and our satellite internet system is on its way...
