I'm over 300' from my house to my shop and with the stock antenna I could only connect part of the time and then at 37 to 45 percent signal strength. And this is after installing the twin 7dbi antennas on my WRT54GS router. After adding just the 7bdi on my PCI card I am hooking up at 67% signal strength and haven't dropped the connection since.Overpriced but it did help a lot in my circumstance.
