Well short and sweet. Is what it says. I bought it from the link below, with connection to a Linksys WRTG54 PCI card. I was using the standard little gimpy antenna. (Designed for home/office use)
Pros: Significantly increased my distance and signal strenght.
Load times and updates seem to be much quicker.
Strong Magnent, not too big on the roof either.
Store provides the cable with any connection you can think of
Cons: Cable provided is about 6 FT long, variable lenghts would be nice.
Overall... 10/10 for performance. It did what it said it would.
