The Hawking 12 dBi Hi-Gain Wi-Fi Directional Window Antenna offers a convenient solution for strengthening and directing Wi-Fi connection signals. The power rating of WiFi antennas is measured in terms of decibels (dBi). The HA12W Window Antenna boosts the antenna power of standard antennas from a minimal 2dBi to a more potent 12dBi. It is an easy to install solution that plugs directly into an antenna port of your wireless device (router or adapter). The HA12W is built with high grade material ensuring maximum quality and performance. This high performance engineering results in extended wireless distances of up to 2 miles. An innovative swiveling window mount allows you to aim your antenna directly towards areas lacking WiFi signal coverage. Whether extending the wireless network from one corporate building to another, or simply from the front house to the back house, the Directional Window Antenna provides wireless users with a high powered solution to extend their wireless network. Installation of the HA12W is simple and straight forward.
