Linksys WiFi Antenna Booster
Emerging WiFi Technologies has come up with this antenna booster that can significantly increase your WiFi signal within your house. The antenna will increase your power output by 1 watt, which is equivalent to a 20db gain for your signal. It is packaged with 2 different connectors that will hopefully allow you to screw it onto your existing unit. There is also a power limiting feature that will make sure you comply to the FCC’s 1000mW power output limits. Compared to the other signal enhancing solution I mention a few days ago, this is a little more expensive. But it is just as easy to install and it will take up less space. Currently it is going for $119.99.
