This antenna increased the signal strength of my desktop's wireless card by 20 dBm. This is partly due to the gain, and partly due to the ability to place it in a better location than a normal antenna.For those frustrated with a desktop disconnecting from wireless because the antenna is stuck behind the computer itself, this is a great solution.It's also aesthetically pleasing, for those who are going to have it prominently displayed on their desk.The only drawback is that it has a 4' cable that is permanently attached to the base, so that it can't be replaced with a longer cable, so extension cords are needed for very creative placement.
