1. If you don't see the antenna, it still has one.
2. The USB cable is not "the" antenna, but I will share I use the extension cables to more the USB Wifi dongles out from under the desktop to where the signal is better.

I would like to purchase a wireless g usb adapter for my notebook. I currently have a Blittz BWU 713. I am on a college campus and am wondering if I should get an adapter with an antenna (like the Linksys WUSB54GP)or one without (Linksys WUSB54G). I will also be using this adapter with a desktop in the future. There is a big price difference between adapters with antennas and adapters without antennas and I want to know if its worth buying an adapter with an antenna. As an alternative is it okay to use a USB extension cable to function as an antenna? If you have any recommendations or suggestions please let me know. Email is: dmpate@wm.edu (the campus spam filter tends to block hotmail).
